While I've no particular dog in this race, I will say that the usual
objection/point of contention here is: who will maintain it?

It was removed because it was bitrotting and unmaintained. Given the
burden it places on active developers to fix API changes, etc, in it,
there's a general expectation that whoever wants this feature must be
actively contributing to the project to, in some sense, pay in kind
for the work that will be necessary on the part of others over time.
