The alternatives are well known and everyone has half a year to actually read about DriverKit and Network Extensions.
Also, why half a year? Do you think it will take them that much to release 10.15.4?
I'm joking but documentation (and tech support) do seem to be dying things at Apple and elsewhere.
Fully agree on the documentation point, though.
And to do that, you have to start much earlier.
How is that enough time?
