Just two cents: perhaps dropping the tag and expanding the commit message a 
bit could be the best of both worlds. Just state that you tested it with such 
and such module, observing such and such results. That would also help if for 
example another user tries a different module and that fails due to some 
quirks: it's easier to debug a potential issue when one knows a working 
configuration to compare a non-working one against.
