I doubt it, most tend to copy Google. And in either case it doesn't
matter that much -- the *vast* majority of our inbound search traffic
is google vs the other searches. By such a margin that it's not even a
point in considering the others.

That we can definitely go. So for recovery.conf it would still work,
but anything that goes on a page where the page still exists, I don't
see how we could separate that out and not do a canonical for that...

AIUI from my reading, Google mostly ignores sitemaps these days. The
only thing it's used for is seeding *new* URLs into the search engine,
not removing old and not having any effect on priority. Probably
because it was abused too much.
