It seems to me that either the warnings are really bugs, in which case
they should be using BUG/BUG_ON, or they're not really bugs, in which

Well, are they bugs or not? I think people are more confused by the
"BUG" prefix and stacktrace than helped by it (even an experienced eye
will glance-parse a BUG+stack trace as a serious oops-level problem
rather than a warning).
