I don't see any reason not to revert it. The benefits weren't exactly
clear from the changelogs or cover letter. Enabling "various compiler
checks" doesn't exactly scream that this is critical to end users in
some way.

The only question is if we revert just this last patch or the whole series.

Uros, is there an alternative to reverting?
