I considered this before approving but my view is that if it is needed,
it is trivial to revert a deletion like this.

I'd generally consider the removal of an unused object to be obvious,
with the caveats:

1. If it looks like maybe it *ought* to be used, then send an RFA
   instead;
2. Be sure to check Insight as it uses a few things that are otherwise
   unused.
