I'll reframe from commenting on my experience with PGI.
Can you point to actual in-the-wild code that uses these
nonstandard forms? Adding something simply because PGI
supports it seems dubious to me.

Do these nonstandard forms occur in DEC Fortran? If not, these
should probably be hidden behind -std=legacy. I tried a google
search for both, but could not find any information.

If the changes are hidden behind an option and you have
done regression testing, I suppose you can submit them now.
The last status report for 9.0 suggested a mid-April release.
OTOH, if you want to follow the rules of GCC, then submit a
bug report, attach the patch, and wait for stage 1.
