Once a branch is declared -STABLE (happening with 5.3 right now) we are
no longer allowed to change or break the userland and kernel driver API
and ABI.  This puts certain hard limits on the ability to MFC changes.

On the other hand it allows the especially the ports team to have better
support the last -STABLE branch because known good applications do not
break with some later -STABLE releases of the same branch.  It is also
a benefit for users because you are assured that your applications don't
have to be recompiled when you upgrade to a newer -STABLE release within
the same branch.
