Someone just earned over 3 BTC with their Umbrel and probably a Bitaxe. I'm celebrating no matter what you say. So OCEAN wouldn't refuse a template that excluded the pool fee?

the network wouldn't which is what's relevant

This is true, but we need more precise language for this. I am once again proposing "sovereign" as the opposite of "hashes someone else's template" while leaving "solo" to mean "doesn't share the block reward". So: - self-hosted Public Pool, CKPool, or datum_gateway without pool split = sovereign solo mining - DATUM on Ocean = sovereign pool mining - using the Public Pool or CKPool servers = centralized solo mining - Antpool Borg = centralized pool mining

A centralized pool like Ocean unilaterally coordinating the coinbase for the entire pool is quite relevant to decentralization.
