I don't mind the warning.

I mind the "more than ONCE" part.

If it's a "this shouldn't happen, but if it ever happens I want to
know about it" situation, then the ONCE variant should be what you
want.

And that variant already existed, and adding a new and inferior macro
seems to just have been pointless.

As to dcache issues - if you really don't get an ack from Al, you can
at least make me aware of it before-hand. That's one of the files that
I at least personally care about, and while I would much prefer an ack
from Al for anything that touches it, at least I'll likely be less
unhappy about changes if I was made aware of them ahead of time,
instead of seeing a pull request that suddenly changes that file.
