Thanks, I see you have found the other patch I was referring to.

Assuming that you are intimate with cp-namespace.c, I might have to
pick your brains for a couple of things that should be possible, but
are currently not.  However with the current homework I've done so

the next DWARFv5 specification first before anything else.
