I don't really have time to do both... I'm already having to heavily
prioritize what I do with Parted.

I'm not sure what the benefits of maintaining ext2resize separately
from Parted are.  I think we should try and put all ext2resize
functionality into Parted.  One problem we might have is Parted's
interface is very simple (read: not very expressive).  Are there
any parameters expert users might want, that Parted can't interface/

It can.  1.3.x has a hack - the "loop" disk label.  Best demonstrated:
