So, the impact of diffraction is obviously NOT independent of sensor resolution. At a given aperture, for some sensor resolutions, diffraction does not impose additional constraints regarding print size (or whatever), while at other sensor resolutions, it will impose additional constraints beyond the constraints already imposed by the resolution of the sensor.

No, that is nonsense.
The diffraction softening may place a constraint on print size, regardless of resolution of the sensor. For ALL same size sensors that is the same. Even with FILM of the same size, the same, regardless of ISO, regardless of film grain.
It may however be that the sensor has such a low resolution that the resolution puts a bigger constraint on print size.
Don't twist it around, as that is nonsensical.
