Well, the good news is that read-only filesystems are _sooo_ much simpler than any real filesystem that quite frankly, on a "complexity" scale it's still way way down there.
Also, if it's not used for backup (and I don't think anybody would), there's actually less reason to be back-wards compatible. I know I changed cramfs a few times incompatibly, simply becaus "you might as well just re-run the user tools to generate the image". It was for a similar need, and the image really always goes along with the kernel.
I think squashfs usage would be similar - you'd not have squashfs as a standalone media, it would be a "installation medium" thing.
