So are you deliberately designing and proposing a solution that is
incompatible with (or not applicable to) an existing interface (FIT FMP)?

Okay, but from my curiosity, how cluttered was it?
It seems to me that you are simply adding extra setup steps.
My simple concern is that, if there is a fair amount of common code
between two tests, it should be unified for maintainability.
