I think the patch is a good idea. Some comments from glancing at the patch.

This seems to break internationalization.

That's currently correct. However, there is another post-Fortran 2008 
Technical Specification in preparation. (Coarray extensions.)* How 
should be handled? "TS 29113 or TS 12345:"?

I'd prefer something like "Legacy extension:" (Or "Legacy:"). 
"Extension" makes it very hard to find the flag in the compiler to 
enable this feature (-std=legacy). Recall that the default -std=gnu 
doesn't include legacy.

I'd rather have something like "Obsolescent since Fortran 2008:". 
Especially when using -std=f2015,* the wording seems to be not ideal.

Additionally, your patch won't work with internationalization. For 
"Fortran 2008" that's probably okay, but for this one, I think it should 
be translatable.
