That is the wrong way to look at it, really.
It is the projected image sharpness that takes a hit. So it is the print size that gets "exploited" or not, totally regardless of sensor resolution.
The only thing sensor resolution can do is: when sensor resolution is too low, it starts to inhibit print size even more than the projected image softness.

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.
