UberPOV has been a collection of features that I expect (or expected) to
not be fitting into the philosophy of POV-Ray proper. Some may make it
into official POV-Ray, others may not. (Just the same as with good old
MegaPOV.)

As far as the new features are concerned, I have not much doubt that
they match the spirit of official POV-Ray; the only reason they're not
in the main branch yet is that they come with a high risk of undergoing
some breaking changes before reaching their final shape.

Another difference is that UberPOV is a /collection/ of experimental
features, while the two new features each live in their own happy little
branch, so...

... that's not too much of a surprise to me ;)
