It's tracked by some national agencies, for example NZ has a deformation model. This link has a summary & links to some lectures about the deformation model: https://www.linz.govt.nz/guidance/geodetic-system/coordinate...

Metres of movement would definitely be significant for a lot of mapping use cases. This is why the time component of any coordinate measurement is important, both due to earthquakes as well as plain old plate motion.

It does but it's just one of many factors that make maps diverge from the ground truth:
