    Perhaps it's just semanthics, but I wouldn't call "still useful"
    to something if no one uses it.

I disagree with you; if something is unused but potentially useful,
we should not delete it.

The whole idea is purely academic, because we have no empirical
way to determine that any feature is unused.  So we don't try.
We don't make our decisions about what is obsolete in that way.
