Attempting to answer my own questions:

(1) Is there still a market niche for XForms as it stands?

Its occurred to me in the past that XForms still has potential for wide use
by becoming something like EPUB. That is to make it a replacement for paper
forms that can be filled in offline, that is as a competitor to Adobe
forms. This would take advantage of the new database capabilities of
browsers to store model data for later submission.

(2) Can XForms evolve to serve this new (apps) need and if so can anyone be
bothered, given the head start of others.

Not a chance.
XML was never meant to be a programming language.
There are no tools for designing XForms forms, I've built a tool to
generate complex ones, but that is a different use-case, it hides XML from
non-programmers.
