Maybe you could say:
1. requiring pTLA /24 and /28 holders to resize to a /32 that begins at
the same address their /24 or /28 block begins.

Assuming all pTLA /24 and /28 holders have allocated their address space
by the beginning of it (that remains to be seen), and that they have
more than they really need, this will achieve the savings in space
without forcing them to renumber (just changing the prefix is a lot less
work).
