you're talking only about SPV proof of transaction inclusion, not about the other fraud proofs necessary for the version of SPV theorized in bitcoin.pdf here's a recent one: https://github.com/bitcoin/bips/blob/master/bip-0180.mediawiki https://github.com/bitcoin/bips/blob/master/bip-0180.mediawi... But why would a miner give an SPV user the data that proves a fraudulent double spend in the same block?

Blocks aren't valid with double spends in them. You are saying the miner makes an invalid block by the rules in order to have a double spend transaction and then mislead the spv client with that information? I'm not making the argument that relay nodes are useless just that their security is being over stated, it catches this particular issue.
