Yes.

No, there is only one correct indentation and both engines should find it.
Also only one engine is important at any given time (if/when the SMIE
code becomes good enough, it will make the other one obsolete).

I don't see any problem with that.

FWIW, the need for such things will largely depend on how configurable
the indentation is.  For cc-mode's hellish configurability there's
probably a need for something serious, but for most modes I didn't find
much need for such details.  In many other cases you can get away with
just setting the indentation vars to "unusual values" in the file-local
vars so that it's obvious enough whether that value is obeyed.
