> "proper datacarrier respecting templates"

Seems like if anything, "proper" would be Bitcoin Core's dafault datacarrier size - 80 bytes. Knots is a fork of Bitcoin Core with a non-standard datacareier size of 42 bytes. Ocean is 100% censoring Samourai Wallet, Sapprow Wallet, & Bitcoin Keeper tx0's. And BIP47 PaynNym notification txs.

Also, Whirlpool CJ's don't use an OP_RETURN so "learn the fucking technicalities".
