I'm very happy about the promise of extended support of the Classic Editor. I'd be much happier if we took this to its logical conclusion and make Gutenberg an optional plugin until it's both a) finalized, and b) in wide-enough use that it makes sense to switch over, instead of forcing people to install a plugin to make sure their website doesn't break. Even if they wanted to make the Gutenberg plugin default in new installations, that'd be fine.

The heavy-handedness of the announcement and plan actually bother me more than the actual plugin itself, because there are always ways to architect around bad decisions. As someone who manages enterprise installations, I have trouble selling my bosses on a product that the maintainer can decide needs a wholesale revamp on, despite it working very well for us as-is.
