An editor is a nonstarter because it doesn't doesn't integrate the right implementation of some particular optional feature for some particular language?
I have some sympathies with the parent post as Zed is my daily driver and I mostly write Python. Pyright is horrible to work with, tons of false positives. Parent poster - you might find this useful: https://github.com/zed-industries/zed/discussions/24801
Well, I mean why use a suboptimal tool? I don’t have any ideology to follow, my codebase is just mostly Python and heavily typed. Pyright doesn’t support all the features so I stick with VSCode/Pylance.
That's a high bar!
