It doesn't really matter why it implies, nolock, I guess. The issue at
hand is that it
does (and always has) implied nolock.  You can't fix that without
breaking things that
rely on it being nolock (like mutter).

Boat's already sailed on this one.  X server already supports a number
of modes that
don't use lock files, and you can't change that without breaking
things in the wild.

Anyway, that aside, they are a bad idea. They create a trivial denial of service
opportunity for users with /tmp access but not local access, they
clutter up /tmp,
and the role they serve is already covered by the more modern
-displayfd construct.
