I defer to your experience as to if and how changes should be made.

if you move to a prepare() method instead of upgrade(), does that mean backend implementations will be responsible for determining for themselves if an upgrade is necessary, and they would do that from the prepare() call?

In some respects that seems to make sense to me because only the backend implementation can know for sure if an upgrade is really required or not.
