The amount of software designed exclusively for Linux grows every day.
Support for FreeBSD is almost always done on behalf of FreeBSD
contributors, not the program developers.

I do not want to play the cat-and-mouse game of constantly updating shims
so we can support Linux software. I would rather take the sensible* parts
of Linux and integrate them into core FreeBSD.

My goal is not to turn FreeBSD into Linux, but rather to stay relevant in
an age where most younger developers don't even know what BSD is. We should
spend more resources on Linux program support, so younger audiences can use
their Discord web apps natively on FreeBSD.

Absorbing "linuxish" bits is controversial and I think that is a tragedy.
In my eyes, having "linuxish" features is one of the best ways to ease the
jump between Linux and FreeBSD, and minimize the maintenance needed for
FreeBSD support.
