Just to expand on that: I think it's also extra broken to then say "..
but we can randomly fix up user space" for it.

It's like saying "we have introduced a totally broken model, and now
we're going to make old applications change because we changed.

That's very much against the kernel philosophy. I realize other
projects work that way, but we really *really* don't work that way in
the kernel. We don't break old workflow unless there is some seriously
overriding reason, and I don't think "we have a new crazy model" is a
good reason.

If the lstat/stat difference made any sense, we could at least argue
for it. But it just doesn't.
