I think that sums it up.

I feel that having them eq? would be "the right thing" but that
right thing-ness in this case isn't a sufficient reason by itself
to change the standard.  Now, if right thing-nness is accompanied
by established practice in more than, say, 80% of implementations,
or widespread support for the proposition among implementors, then
I'd be for changing the standard to require it.
