I was saying that sometimes there are configs that can be shared (enabling electric-quote-local-mode, for example), and it would be nice to put them in a single hook rather than duplicating the code in two hooks.

I’m talking about sharing the sharable config. Electric modes already work the same in ts and non-ts modes: electric-pair-mode and electric-quote-mode inserts matching pairs and quotes and aren’t affected by tree-sitter, electric-indent-mode uses the standard indent-line-function which both ts and non-ts modes confront to. Is there any other electric modes?
Also, ts modes generally have the same syntax table as non-ts modes. So if some package uses the syntax table they are largely not affected either.
