Comment (by Thunderforge):

 One note about this: not all version updates result in incompatible saves.
 For instance, Wadjet Eye Games makes a point to only create updates that
 will preserve saves. Based on discussion on their discord Discord, I've
 gathered that modifications to game world objects do invalidate saves, but
 dialogue changes do not. I'm sure there are other nuances.

 So if this is ever implemented, we can't just naïvely say "different
 version means incompatible saves." I think it would have to be done on a
 case-by-case basis, unless we can develop a way to programmatically
 calculate that two versions will create different saves.
