What I'm concerned about is making such a fundamental semantics change
post-beta1. It'll basically invalidate any application compatibility
testing anybody might have done against beta1. I think this ship has
sailed as far as v16 is concerned, although we could reconsider it
in v17.

Also, I fail to see any connection to the MAINTAIN privilege: the
committed-and-reverted patch would break things whether the user
was making any use of that privilege or not. Thus, I do not accept
the idea that we're fixing something that's new in 16.
