I have added the FreeBSD x11 team alias to CC, which I probably should
have done in my original email. They are in a better position to answer
this than I am.

At present, MySQL also does this. Changing that would require changes to
the userland of FreeBSD (and other BSDs). The FreeBSD x11 team is in a
position to do that. I am in the process of getting Gentoo's X11 stack
working on Gentoo FreeBSD, so I am interested in their answer to your
question as well.
