That's a good idea. I considered VSCodium but the issue is that I used VSCode's proprietary extensions such as Pylance. So it would require to switch to OSS replacements at which point I decided why wouldn't give Zed a try – it has a better feeling by not being an Electron app. I think VSCodium is a good option if you need extensions not available in Zed.
Basedpyright and ty should both work under vscodium.
I appreciate that we have good alternatives to pylance. While it is good, it being closed source is a travesty.
