Great summary!
Any idea how the different plate motion models behave near plate boundaries? There are a few plate boundaries in areas that are interesting for human users. The East African Rift Valley is famous, but there are others as well.

For anyone using these kind of transformations, the boundary between the preferred models for two countries may well be discontinuous!
Ultimately the correct way to deal with this is to use a global time dependent deformation model. Some countries with large internal deformation have already gone to the effort of producing local versions. For example New Zealand: https://www.linz.govt.nz/data/geodetic-system/datums-project....
I guess there will eventually be a high quality global deformation map available but I wasn't aware of any such thing in general use as of two years ago.
For example, a polygon that becomes self-intersecting because some of it's points are on different plates.
Thats bad for linters and database constraints...
