I suggest a slightly different solution: add a global minor mode, say 
'ts-modes'.  Users would only have to add (ts-modes 1) in their init 
files, and the logic would be:

(treesit-available-p) ts-modes
nil                   nil      => do nothing
nil                   t        => warning
t                     nil      => use available tree-sitter modes
t                     t        => use available tree-sitter modes

This seems more future-proof: otherwise users who want to user the 
available tree-sitter modes would have to require all such modes.  ATM 
there are only 19, but Emacs 30 could very well have twice or thrice that 
number of tree-sitter modes.
