I want to kill all non-BFD_ASSEMBLER gas targets, to reduce the
maintenance burden, and allow BFD_ASSEMBLER gas targets to be cleaned up
without worrying about breaking the old code.  That will mean the
generic support code in gas for non-BFD_ASSEMBLER will disappear from
mainline.  Whether the corresponding tc-* files disappear or not doesn't
matter so much, but I favour complete removal.  You won't be able to
build these gas targets until they are converted over to use BFD.

More generally, I think we should remove targets that don't have active
maintainers listed in binutils/MAINTAINERS.  Again, this is simply to
reduce the maintenance burden.  Occasionally when making a global
change, I'd like to be able to email someone and say "xyz has changed,
please fix it for your target", rather than having to dig through some
crufty backend code myself.

OK, I guess that's reasonable.  Please list yourself as a maintainer
in binutils/MAINTAINERS!

No.
