This is the first time I've heard of this standard and it looks interesting, but it doesn't seem like the payment processing is well standardized. I see in the W3C draft that the "Interledger Protocol" should be utilized, but looking at the wallet limitations (https://webmonetization.org/wallets/#limitations) it seems like there are no wallets that allow cross-wallet payments. Is that something thats planned in the future, or will wallets be allowed to lock down who can pay who?
This is not a "standard." From their documentation[0]:
And nothing about the "Web Monetization" primary intent[1] is appealing as a standard worthy of being adopted: 0 - https://webmonetization.org/developers/link-element-webpage/...1 - https://webmonetization.org/
