That would be my preferred solution -- by far.  But, my understanding

Hopefully, it is it is going to be the default, most people would not have
to learn yet another GCC switch.


Why to introduce a new switch then?  Just select a few -W switches and enable
them by default, keeping in mind that -w will disable them in any cases.

I think the idea is just to have an easy way to describe the relevant set of warnings, and a specific way (-Wno-standard) to go back to the status quo.
