Supposedly, you just install this and you're good to go: https://wordpress.org/plugins/classic-editor/

I just tried updating to 5 on a test copy, as far as I can tell it didn't break anything.

The drop in boxes on 5 were too small on my system to edit (looked like it had a max width of 600px. This essentially forced my hand for the classic-editor because I couldn't drop in images and what not. Really strange error to have on the first day.

The boxes for editing should be based on percent (I shouldn't have to edit them).

For as long as that plugin is supported..
