I like that they aren't creating a new standard that wraps over all of them. Rather, they're just adding ways to specify which standards you prefer. Simple.

"Payers can specify which payment method they prefer as well as request multiple payment type options they can pay to.

For example:

Alice wants to buy an e-book from Bob.

Alice uses Bob’s Slashtag (pubkey) to look up his DID document on the Hyperswarm, learning which payment methods Bob supports.

Alice happens to be able to pay with native segwit, taproot and Lightning, but Bob only lists native segwit and Lightning.

Bob sends Alice an invoice for the desired payment amount on Lightning, as well as an address for paying that amount into a unique native segwit “bc1q…” address.

Alice pays Bob over Lightning, Bob delivers a receipt proof, allowing Alice to retrieve the e-book from Bob."

I have always wanted to see more cool stuff built with hyperswarm and their DHT network. Will definitely check this out!
