It's interesting that the #2 selling point on the landing page (the Copilot integration) relies purely on Microsoft's goodwill. There is no official API for Copilot but instead a (non-standard) LSP implementation embedded into the proprietary Copilot Neovim plugin. Zed seems to trust under the hood that a release of the plug-in exists on Github, pulls the minified-js language server from there and integrates with that. The minute MS decides to pull the plug on the Neovim plugin Zed loses the functionality as well.

I wish we had a proper API to interact with copilot but it seem that pulling everyone else except the dedicated VIM and JetBrains users into VSCode land seems to be more in their interest.
