I don't read that.  What I read is that new X11 requests should no longer
be accepted, but that existing (_already opened_) forwardings should live
on.  The point of the paragraph is to note that just because an already
opened [X11] forwarding is left open, doesn't mean new X11 requests must
be honored.

Interesting that the text does not capitalize SHOULD and SHOULD NOT.

No, but they deal with this case.  My suggestion was just that you discuss
it with an implementor that has addressed it.  But now that I have a
clearer idea of what you're asking, maybe this list is more appropriate.
