In fact, the effort and time spent on adding more and more warnings about style
would be better spent on creating a gcc-tidy tool. Even adding a flag for an
existing warning has a cost.

Having a gcc-tidy tool would benefit gcc by encouraging abstraction and
modularization, and benefit users by making easier to add any particular style
warnings.
