Why? What has *anything*else* got to do with fixing a NFSv4 bug?
IOW, why the hell would we hold up one bugfix just because you might
want to look at something else too?

Umm. If there is any question at all what the correct behavior might
be, then pretty clearly the correct behavior is to let the user
decide.
And as pointed out, that's one of the *advantages* of
LOOKUP_DIRECTORY. Because it lets users decide.
Exatly because it gets automatically set for the 'slash at end of
name' case. So suddenly you can literally let the user say one or the
other by just letting the user add or remove the slash: "/mountpoint"
is not automount-followed, while "/mountpoint/" is. Nice, obvious, and
consistent interface. Which is exactly what we'd be looking for.
