I'm not sure a global toggle would make sense at this time: even if the user
has the tree-sitter library installed, there's no guarantee that the grammar
for a particular language is also installed.  Only the user knows whether it
is or isn't.  Enabling a mode just to get an error message makes little

Perhaps in the future distros will catch up and provide installation of
grammars that includes everything available, but until they do, we are
better off with individual toggles.

There's also a question of user preferences: some might prefer the
non-TS versions for whatever reasons.

IMO, per-mode toggles is currently the best compromise, given that we don't
yet have enough user feedback and experience to decide on more general
