I can see why people would be concerned about this but there is a limit to what SE can actually do about it. Theoretically something like a Mega server might hold solutions but that can hold as many cons for community as it does pros and isn't a minor technical feat to convert to even if the game engine is capable of it.

In short there isn't much they can do to fix it. Just leaving things with transfers as they are will raise only more issues. Sometimes the none of the realistic options are ideal. The best that can be done is for the community to try and adapt to the changes.
