What do you think of a protocol extension for SPV style chain download of the subset relevant for one's wallet?

A node would query SPV style proofs for transaction inputs relevant to it until proofs reach coin bases or verified by previous proofs.

Wallets don't need to know the dependencies of their own transactions, so I don't see why this would be useful.

It would be useful for applications that care of the origin e.g. colored coins.

Applications that care about origin, colored coins in particular, are already very SPV compatible; you're just looking at it from the wrong direction. What they could do is start with the genesis transactions and scan the chain forwards, rather than starting with a alleged colored coin and scanning backwards.
