True, if you don't need the kernel-side to support it you can use arbitrary complex delta approaches to optimize the download.

Also, you can use filesystem level compression (in e.g. btrfs) to compress the files in the backing dir. Or even use reflinks copy create backing files that share some (but not all) blocks.

The sky is the limit, and all these approaches are compatible with using composefs to mount them.
