We do things this way in Flycheck, but we've been bitten a few times by the way this pattern interacts with `with-eval-after-load`, so I would be careful about adopting this pattern in tree-sitter (unless we expect it to be preloaded).
In fact, I think your suggestion back then was to *not* use a macro? I can't find the exact thread, but this is close enough: https://lists.gnu.org/archive/html/emacs-devel/2018-02/msg00820.html :)
