my idea was to have editor extensions register themselves as providers of an editor for arrays of content models, then show those as options to the user prefs, and have the user prefs decided which toolbar to show for which content model.

That is partly based on moving the 'classic' toolbar out of core and into it's own extension. It's quite a bit of work.

This seems like a good idea, and it's one several people have discussed. Let's explore it.
