Extensibility is key, and we can’t build the next generation of the WordPress Editor without making it extensible. What does “making it extensible” mean? Does this mean providing hooks and filters in JavaScript the same way we do in PHP? Does this mean allowing plugins to extend and tweak any UI component used by Gutenberg? Does this mean adding filters to the REST API? Does this mean Giving access to an Editor object to manipulate the editor’s content?
There’s no clear answer to all these questions. Extensibility is a very difficult problem and unless you build it with real use-cases in mind, you’re more likely to get it wrong. (and being stuck with it for a long time).
