I have a simpler suggestion:

every attribute whose name starts with an underscore like "_user" or
"_foogreen" or "_BORING" never produce any warnings, except perhaps in the
plugin handling it.


Yeah.  Or perhaps a variant of this.  Allow -Wno-attribute to take as
argument the name of the attribute you want to ignore.

I am not convinced that exactly is a very good idea. I would expect that with plugins, we'll have significantly more attributes. I don't know if having a really big CFLAGS (in Linux Makefile parlance) is a good idea.

The proposed underscore notation is quite simple, and suggest a notation to separate the important attributes (those handled by GCC core) from the other ones.

A more sophisticated variant would be to have every attribute belonging to some attribute class, and have Wno-attributes=attributeclass but I feel that is too complex!

Regards.
