Not AFAIU, no.  It is an implementation of a different indentation
method.  I don't see why we should want to go that way, since there's
nothing wrong with the existing algorithm, except for handling of
variable-pitch fonts.

More like because the existing indentation algorithms are okay, and I
see no need to change them to something else.

Yes.  It isn't different from what happens when you change tab-width.

Not sure how that is relevant.  A different indentation convention
will look differently, of course.
