That said, I've noticed something when building the feature/tree-sitter branch, and also while testing other things tree-sitter related... If a language-definition SO is missing... treesit.el in Emacs only reports looking for files and folders typically found within $HOME/.emacs.d/ (that is user-owned files).

Based on that, I'm assuming those are the only locations probed. Is that assumption correct?

It shouldn’t be. Emacs should first look in treesit-extra-load-path, then ~/.emacs.d/tree-sitter, then standard system library locations. The exact locations depend on dlopen. Could you share the error message reported when loading a non-exist language? It should print all the locations it tries (as you observed).

textmodes/mhtml-mode.el:29:2: Error: Cannot load language definition: "_javascript_", ("/home/jostein/.emacs.d/tree-sitter/libtree-sitter-_javascript_: cannot open shared object file: No such file or directory" "/home/jostein/.emacs.d/tree-sitter/libtree-sitter-_javascript_.so: cannot open shared object file: No such file or directory" "libtree-sitter-_javascript_: cannot open shared object file: No such file or directory" "libtree-sitter-_javascript_.so: cannot open shared object file: No such file or directory")

Does that impliy it checks in the standard system library localtion? If so, I guess there's no problem.

In that case, sorry for the "noise", but I just wanted to make sure this was packagable and thought one check too much is better than one check too little :)
