Clang is smart enough to propose using override, but only if it see that it
was used somewhere, so it is not totally enforced. Also I don't think it
warns about redundant "virtual" if one writes "virtual void foo() override".

Yes, the bitfields is the only one reason we would need initializations in
constructors in some places, but it is rare (as far as what clang-tidy
check have found)
