Additionally, on the flip side, I feel a single rod capable of shutoff will insert excessive positive reactivity in case of an ejection (could be a local steam overpressure, idk, don't hunt me down with hounds).

You planning to keep the service up, it must be costing a pretty penny under the hood?

It's the reactor reactor-ing within the design basis. But, I think "single rod-drop" will not shut down a reactor. That's a crazy amount of rod-worth. My opinion is that reactor safe-shutdown margin entails "single rod-stuck" scram to be feasible.

The former is an interference/diffraction effect while the latter, is you underpinned earlier, is a sort of spatial heterodyning effect. For instance, you can generate moiré rulings (which effectively an optical illusion) with two angularly misaligned combs, but the comb spacing is order of magnitude larger than optical wavelengths, leading one to conclude it's not a wave interference phenomenon.
