Hmm... that's not information I/we had in Oct 2002 when we made
this decision. It makes me think about the issue differently.

As far as I can see, the changes would be non-trivial, but
not very big.

I don't think I have bandwidth to champion the cause, but
if a volunteer to own the issue (i.e. lead the discussion,
perhaps come up with a few examples for the guide and/or
test suite, review changes to S&AS, that sort of thing)
emerges, I'd like to see us quickly reconsider this.
