Re/ the QZE: An ideal physicist would write down a suitable model Hamiltonian for the unstable atom + detector + EM field + environment, and then compute the relevant decay rates/probabilities for some time of interest. This "shut up and calculate" procedure isn't contingent on the acceptance or rejection of any interpretation, statistical, minimalist, or otherwise.
What makes QZE interesting is the challenge of shutting up and calculating: the construction of the model Hamiltonian and the computation of decay rates etc. From https://arxiv.org/pdf/quant-ph/0307075.pdf:

Naively projecting here and there is not a feature of an interpretation. It's a feature of poor application of a theory.The latter condition explains why the QZE was not obtained for exponentially decaying systems by theories based on the projection hypothesis. By applying the projection operator, the quantum coherences between |x, 0〉 and |g, k〉’s are destroyed regardlessly of the energy of the emitted photon. Therefore, the projection-based theory corresponds to ∆ → ∞ [20]. In such a limit, however, inequality (10) cannot be satisfied and the QZE never occurs. Since ∆ of any real detector is finite, such a limit is rather unphysical.
