I think a buffer-local `treesit-mode` plus a `global-treesit-mode` would
make a lot of sense, from a user's perspective.  This way they don't
have to hunt for the name of the boolean variable that their mode
decided to use to control the use of treesitter: all modes use the same
boolean variable called `treesit-mode`.

Then again, to me a minor mode is something so cheap that the idea that
"justification for a minor mode was too weak" is rather hard to grasp.
