Ok I'm putting my tty maintainers hat on at this point because nobody
seems to be listening

I'm NAKking this change, I'm NAKking the feature-removal change.

If you want this to change convince the distributions there is a point in
supporting it. This is the *wrong* forum to force a cornercase feature
onto a bazillion users, and the wrong way to strongarm maintainers of the
relevant user space.

If udev has a problem handling it nicely because of the way the link is
generated then *fix that problem* so udev automatically gets both cases
right. If need be we can add more messages to udev to tell it what is
expected and what devtmpfs should produce.
