Nothing specific, no.

Automated editing and/or import guidelines would apply to any such
process and I would ask everyone who overhears discussions about
"uploading" machine-detected data to OSM to point this out to those
discussing. We've already had to revert a couple hundred thousand such
edits (roads though, not buildings).

If, OTOH, an editor plugin were to help the mapper trace buildings that
the mapper identifies or at least individually verifies, that would
probably be ok, at least until HOT trains an army of monkeys with
typewriters, er keyboards, to rubber-stamp everything the algorithm puts
out ;)

More generally speaking, in my opinion the human-centered aspect of
mapping is a key property that sets us apart from other map databases.
You can safely assume that any algorithm we can run to detect buildings,
Google can run 1000 times faster and with a fraction of the error rate,
leading to 1000 times more and 10 times better data of that kind than we
can accumulate. This is not a field in which we can, or should attempt
to, compete.
