My view is that changes that silence compiler warnings are
not fixing bugs and that these changes should generally not
be backported.

Compiler silencing changes marked as fixes can introduce other
defects in working code.

Backporting patches to stable trees should be conservatively
rather than liberally applied.

It seems that the actual backport maintainers disagree though.
