Don't other BSD kernels do something similar?

I think Linux always adds new syscalls under a new name, even if the
old replaced one is deprecated.

I'm fine with it as well.  It just felt like if the we could keep it short, it'd
avoid fragmenting the information.  IMO, a user reading the "catch syscall"
bits in the manual isn't going to remember to look up the FreeBSD-specific info
in a different node.  Unless we add some xrefs.
