Why wouldn't they?

No reason beyond that it requires extra code in pacman to make it work. It could be a thing that's easily overlooked.

I believe signatures are checked after packages are rebuilt from deltas. Therefore, if your delta is compromised, the resulting package won't validate with the signature.

Excellent. I also notice you use the word "deltas", plural, which leads me to the next question :)
Will deltas be combined by pacman, or will only ever a single delta be used?

They can be combined. pacman does a calculation to see whether the delta chain is worth it.
