Yes, my thing should probably be on that list.

OK.... (?)

Yes, yes, and yes. Please see

Thanks.

It's not hard, really; just a bunch more typing. Do you want to add it? It's
formulaic ;-)
If not, I'm sure we could get it enabled in the next few days.

We control the attribute lookup/function calling/error reporting rules for
the ExtensionClass types, so we can do almost anything we want.

Thank you for so generously understating the case.

I didn't mean to imply that. I meant to imply that if you have exposed C++
classes Base and Derived, and a C++ function declared to take a Base&
parameter, you will be able to pass a Derived instance from Python.

Your feedback has already been valuable, thanks. Just make any further
comments to the list.
Thanks,
