The key, IMO, is : how many gurus will there be.

Currently, the maximum a user can do is a complex macro.  There is a 
good proportion of users who can do that, but these are "small gurus",
since the system doesn't allow them to go very far.

Currently, if someone wants to do more, he have to either write an
external utility (which might be cumbersome to use, hardly portable...)
or do a POV-Ray patch, which requires even more competence.  These
are "big gurus", but represents a smallish fraction of users.

If the new SDL allows enough power while keeping a smooth learning
curve, there can be many "medium-to-big gurus", and everyone would
benefit from these developments.
