The more time we spend discussing what the ideal should look like, the less time we have to actually get there. The current eldoc-async branch doesn't get us further from the ideal, I believe, unless `emacs-28` gets cut before we get our act together. But if we don't get our act together before `emacs-28` then the alternative is to have Emacs-28 without support for async eldoc, which I think is even worse. I recommend we try and be pragmatic. Especially since it will make us all happier (instead of arguing against each other, we get to work on improving the code). Stefan
