I figured I'd try for a solution that didn't offend my sense of
aesthetics before caving in and working out how to better document the
limitations of the status quo :)

Since this is really just a matter of the aesthetics of the underlying
design from my point of view rather than solving a real world problem, I
don't have a good answer for you.

In the absence of reports of actual problems caused by this limitation,
should I consider the PEP rejected?

Cheers,
Nick.
