Another way of looking at is "we know it's been broken for six months, and
clearly nobody really ever enabled it in any distro, and even getting a
bug report on it took forever. So why keep it around at all"?

So I'd personally rather just remove it outright than deprecate it or even
try to fix it. Since clearly absolutely nobody depends on it.

The usual reason for deprecating a feature is to give people time to move
away from it, but since clearly nobody uses it...
