Leonardo Losoviz is pretty excited that Matt Mullenweg expressed interest in having WordPress’s editor comply with the Block Protocol:

My excitement comes from what happened with GraphQL, where the release of servers, clients, and tools adhering to a common specification has produced a rich ecosystem; and from my own development of a plugin that could support new features through the protocol.

Don’t fret if you’re new to this “Block Protocol” concept, like myself: Leonardo starts off this (long) article with a nice explainer before he gets into the potential outcomes of WordPress’s involvement.
