High probability.

These systems (FreeBSD, NetBSD, OpenBSD) diverged over 20 years ago and
are developed by different teams and for different use-cases.

We should assume that these systems are completely different POSIX-like
systems, with shared ancestors (AT&T UNIX -> BSD UNIX).

Thought, DragonflyBSD & FreeBSD are relatively similar, FreeBSD fixes
should work for DragonflyBSD in most cases.

Right now there are no other modern BSDs with a vibrant community,
everything else is retro-computing, remix with preconfigured desktop,
hobby, 1-man-show etc.
