It's a shame when a patch creates lots of warnings and they are ignored. I would suggest that the patch should not be merged. :) We should at least bring the warnings to the attention of the patch author. Sure, in some cases we (I) might make a patch that the author wouldn't want and would have better solutions for. That's OK. It happens often.
