Right.  If the feature was never documented, it might be the case that
no one is using it, or are not aware of it, and that therefore no one
noticed that it's bitrotted.

I'm just asking the question based on my observations.  I don't see a
use-case for this feature, and if it is indeed broken then the fact that
no one has complained might be some indication.

If you think that this feature could be useful, then I have no objection
to keeping it.  But if it is indeed broken, it should at least be fixed
to work as intended, and then documented; preferably in that order.
