That would be nice. It only affects C++2a code. There was a follow up
patch that tweaked the same C++2a features, and added a new test (to
verify functionality that was already there, but untested):
https://gcc.gnu.org/ml/gcc-patches/2019-04/msg01046.html

Is that OK too?

And I'd also like to backport this patch that only adjusts some tests
so they work with the old string ABI:
https://gcc.gnu.org/ml/gcc-patches/2019-04/msg01059.html

OK for gcc-9 too?
