Sure.

Not sure I understand what you're saying here. Perhaps you and Matthew
are talking about different things after all.

But for Matthew's issue, the case where the bots are testing posted
patches ("Thank you for the patch! Yet something to improve:) should be
easy to fix by simply dropping or rephrasing the "kindly add following
tag as appropriate" suggestion.

When testing merged code, it may be harder to tell whether the branch in
question can be rebased or not (and an incremental fix with a
reported-by tag is warranted).
