Then a user doesn't really getting a useful major mode for editing Rust
files or other programming files when using their *-ts-mode (without
their grammar installed, that is).

Other non-ts based modes, though less accurate, are readily usable after
`M-x package-install', which IMHO is slightly more new user friendly.

Of course, if Emacs provide a built-in way to install the grammar
libraries automatically that would be better.
