I think a better way to phrase this criticism would be to say "please
next time mark your series as RFC and mention in the 00 covering note
the issues which mean that the series should not be applied".

It is definitely appropriate to post RFC patches even if some
important parts are missing.  What is necessary is to explicitly
discuss the problems, so that they don't get overlooked.
