Sounds good. Indeed, for this feature a registry of opener-closers 
should suffice.

Another command that could use it, is an implementation of 
backward-up-list. Somehow the default up-list manages to use SMIE's 
forward-sexp-function (and backward...) definitions automatically, but 
not tree-sitter's. I've been told it's expected for now, so I think 
opener-closers are the missing piece (either to enhance 
treesit-forward-sexp/treesit-backward-sexp to resemble the originals 
more closely, or to implement treesit-backward-up).
