Feel free to send a patch for that.

SO_BSDCOMPAT has had ZERO side effects since 2.0.x, and it's been
thus scheduled to be removed for years.  It was merely a binary
state passed in and out of the kernel to the user and had no effect
on socket behavior at all.

Any application still referencing this ancient thing either expects
some kind of different behavior from setting SO_BSDCOMPAT non-zero,
or really doesn't rely on anything at all.

Since SO_BSDCOMPAT has had zero side effects for 5 or so years, this
means that the safe change is to remove all references to SO_BSDCOMPAT
that exist in any application.
