Would people even notice such a warning?

People who are using long-term keys and inserting them into the kernel
build probably ought to be paying attention and know what they're doing.
There are relatively few of them, and I think that as long as the change
is clearly documented, we should probably be fine.

Besides, *anyone* relying on that horrid wildcard crap should have
*expected* it to go away because it was an abomination :)
