Could be.  But using `widen' is a simple solution to those problems
(until you bump into problematic cases like Rmail and Info where
`widen' ends up widening too much).

BTW, a good start might be for someone to sit down and design a sane
way for narrow and syntax-ppss to interact.  If that includes a cleanish
way to support multiple modes, then it's even better.

Still: why do you want to avoid LEFTMOST-COL at all?

I don't see how that influences the usefulness (or not) for
LEFTMOST-COL.
