If we go this way, I would like to see some object-oriented capabilities (e.g.
the ability to create an object and instantiate it multiple times with different
attributes rather than wrapping it in another object { } block)

I would also like to see recursive function definitions, but not knowing how
complex this is, I consider it secondary.

The problem would be that any major enhancement to the existing system is almost
certain to be a rewrite anyway, so why not use a new language (except that it
would completely break old scenes and necessitate rewriting current projects.)

the problem I see with this is that not all of us are good at this sort of
thing.  If this is the direction povray were to go, then I think it would be
better to have a plugin system so that, rather than compiling dozens of
unofficial versions of POVRay, we could have One Ring to Rule Them All, and
extra functionality -- even overriding functionality -- could be handled via the
plugin system.
