One thing to be cautious is that all *-ts-modes require tree-sitter
syntax libraries to be available to use, which are not shipped with
Emacs.

One can follow the instructions on masteringemacs[1], or install
treesit-auto[2] to install tree-sitter syntax libraries, which are not a
lot of trouble but may still be more work than a new comer would expect.
