QFT is relativistic quantum mechanics with fields i.e. a continuous limit of a lattice of harmonic oscillators, which you may have encountered in solid state theory. It is the framework for the standard model, our most rigorously tested theory by far. An interpretation of quantum mechanics that can’t generalize to QFT is pretty much dead in the water. It would be like having an interpretation of physics that works for classical mechanics but can’t generalize to special or general relativity.
(Edited to change “more rigorously” → “most rigorously”.)
