[Just to be clear, the context of my remarks is changes to .cpu/.opc files.
Nothing else.]

A port maintainer is a port maintainer.

If redhat is the port maintainer for xstormy16 and checks in something to
xstormy16.cpu because they need to change binutils and later find out
they've broken gdb(sim) it's a problem of their own doing.  They can undo it.

Similarily for any port maintainer.

I don't understand.  The context here is .opc. files.
Changes to .opc files don't affect sid or gdb.  Only binutils.

I'm not sure I would word it that way.  Maybe it's ok, I dunno.
uber-hackers in binutils/gdb may be able to make port specific
changes as they deem necessary (are they?).  I'm not sure this should extend
to .cpu files.  But I certainly have no problem with authorized
port maintainers of binutils/gdb making changes to cgen port-specific
files (provided of course they're willing to work through any problems
that may arise).

Given the above seemingly misunderstandings, just so we're clear,
"port-specific changes" means changes to files in src/cgen/cpu
[or whereever they move to].
