The general shape looks plausible, but it needs to continue working even
with Xen 4.6 and older.

Not sure how best to achieve that, perhaps checking for the existence of
some well known piece of the Kconfig infrastructure and behaving
accordingly?

Another alternative would be to add a runvar (see osstest.git/README for
the terminology) which controls whether Kconfig is to be used expected, but
given that this is static and per branch I'm not sure there is too much
point in this case (and it would be more complex for a newcomer).

Ian J probably has an opinion.
