Has it though? I interpret this to mean that by the default, settings will be structured in such a manner to support the inscription spam. It’s just that now, we node operators can manually change a certain config setting to opt out of that crap. 💩 But those who don’t opt out will happily relay and store the spam by default. Or maybe I’m missing something?

Well if the PR had passed then all node operators would have 0 settings and choice to filter anything... So any 💩 would be allowed by default by all node operators without any way to change any settings.
