I don't agree that it is nicer to do this in cramfs.  I prefer the

recipe for bugs and feature mismatch.

You're right in principle, but unfortunately there is to date no working
implementation of union mounts. Giving users the option of using an
existing file system with a few tweaks can only be better than than
forcing them to use hacks like unionfs.
