I believe Val used ext2 as a proof-of-concept, because the codebase was stable (and Union Mounts has been in the oven a loooong time, so that was probably a good choice). I agree that if union mounts is finally going to make it upstream, this would be a good time to support implemented for ext4, and to get the support into e2fsprogs.
BTW, one thing that I think would be a good thing to do while we're making this change is to mask off the low 4 bits when looking at the filetype field so eventually we can use the high 4 bits for some future extension.
