But PP isn't practical for video and many users do not want to spend hours denoising their still images.

The large A7s pixels are otimized for video, says Sony.

Ah, that is a whole different ball-game

For video one can imagine that the lower pixel-density of the A7s is genuinely useful and there is no point in ultra-high resolution sensors for that application (unless you are using a 'digital zoom')

For still photgraphers there is little or no difference in file handling and noise reduction/post processing for images that are scaled to the same size, no matter if the sensor is 36, 24 or 12 Mp.

I would expect some more well depth for large pixels, which would result in a bit better dynamic range - but nothing that really make a noticeable difference at very high ISO settings.

Yes, that's the read noise, but it is apparently much less important than the shot noise

This assumes that the sensors employ the same level of technology...  if the lower pixel density of a 12MP sensor allows the implementation of a superior technology in the way the pixel sites are fabricted then there might be some genuine benefits
