In the case of silent payments, however, you don't share your xpub at all, replacing it with a deterministically derived silent payment address, which is basically a hash of a public key (not a master public key) encoded in a special format. In the latest implementation, it was proposed that silent payment addresses should start with the "sp1" prefix.

I know; just wanted to point out that xpub sharing (as alternative to silent payments) is not only less private but also potentially insecure.
Where can I find more information about the latest implementation or proposal? I'm interested to see what the creators think / how they handle SPV wallets and the complexity / burden of scanning for transactions.

Your schema remember me what in Monero is called Stealth Addresses:

Maybe this can be useful to compare the ideas:

Yes, this is exactly what sprung to mind when I read this proposal. In my opinion, the biggest disadvantage - just as in Monero - is the need for transaction scanning.
