I've changed my mind. Those warnings should be removed from the
message log, and shifted off to the console only.

See https://github.com/qgis/QGIS/pull/6991

I didn't realise how slow they made rendering until I hit this same
issue on a recent project, and the cause was the labeling feature
cropping, so not even anything which is user-fixable.
