As part of macOS Catalina 10.15.4, Apple has begun displaying a new dialog window message concerning third-party kernel extensions.
[…]
To further reinforce the message that kernel extensions are going away, Apple refers to them in the message window as “legacy system extensions”.
[…]
For a number of managed environments, these messages can be prevented from appearing. As long as a third-party kernel extension is whitelisted using an appropriate configuration profile, the message for it should not appear.
Norbert Heger (Hacker News):
We expect the deprecation to become effective with the next major release of macOS. There’s no official release date from Apple, but based on the release schedule of recent years it will not be before this fall. Little Snitch 4 will then not be loaded by the operating system, but there will still be an option to allow the loading.

The replacement APIs that are currently available (NetworkExtension framework on macOS 10.15.4) are not yet completely sufficient to implement the full functionality of Little Snitch. But we are working closely with Apple to fill the remaining gaps and we expect that a beta of the next major macOS version (most likely available at the next WWDC) or even an upcoming version of 10.15 will provide what is missing. As soon as the APIs allow us, we will complete the transition of Little Snitch to the new NetworkExtension API. It’s our goal to provide a public beta in June 2020 and a stable version in October.

I sure hope this doesn’t end up breaking Karabiner-Elements. If I had to use a machine without it, it would seriously impact usability for me. When the day comes that Apple breaks kernel extensions once and for all, I’ll be holding off on OS updates for as long as I can.
Adam Engst:
Unfortunately, since the dialogs give only the developers’ names, not the names of their apps, it’s difficult to know who I might contact. A Google search revealed that Ludovic Leger is the dev lead on TripMode, a useful utility I recommend for managing bandwidth use while away from high-speed networks; see “TripMode Prevents Unwanted Internet Data Usage on a Tethered Mac” (22 July 2015). I’m still not sure who Steven Yan is, or what app of his I might be using. That’s not a problem now, but it might be in a few months once the beta of whatever macOS version follows Catalina comes out.

You probably came here because your Mac showed a message telling you that software from “Objective Development Software GmbH” (Little Snitch) loaded a system extension that will no longer be compatible with a future version of macOS and that you should contact us, the developer, to get more information. Well, here you are.
In order to be able to perform filtering of network traffic, Little Snitch 4 installs a kernel extension (the above mentioned “System Extension”) which is based on Apple’s “Network Kernel Extension” API (NKE).
This API will be deprecated in a future version of macOS and replaced with a new “NetworkExtension” API (NE). Despite their similarity in name, these two APIs work very differently, so the underpinnings of Little Snitch do require a substantial rework.
Will there be an updated version of Little Snitch that is compatible?
Yes. We are going to release an update of Little Snitch that will utilize the compatible replacement APIs.
When will Little Snitch 4 become incompatible?
We expect the deprecation to become effective with the next major release of macOS. There’s no official release date from Apple, but based on the release schedule of recent years it will not be before this fall. Little Snitch 4 will then not be loaded by the operating system, but there will still be an option to allow the loading. [1]
What happens in the unlikely case that no updated version of Little Snitch is available at that time?Little Snitch 4.4.3
We do our best to have an updated version available right in time. But if you’re still concerned – keep in mind that there will be an option in macOS to allow running Little Snitch 4.
If I buy Little Snitch 4 now, will I get the update for free?
Yes. All licenses sold now include a free upgrade to Little Snitch 5. In addition, customers who purchased Little Snitch 4 within a one-year period prior to the final release of Little Snitch 5 (about this fall) will also get a free upgrade. And if you purchased Little Snitch 4 before that period, we will offer you an upgrade at a reduced price.
