Won't really help ya. As outlined at https://ghuntley.com/fracture/ as soon as you compile "VSCode" (MIT) the ecosystem fractures in a bad way (tm) including no-license to run majority of MSFT extensions (Language LSPs, Copilot, Remote Development). If you are a vendor producing a MIT fork then one needs to iterate the graph and convince 3rd party extension authors to _not use the MSFT extensions_ as dependencies _and_ to publish on open-vsx.

This is how Cursor gets wrecked in the medium/long term. Coding agent? Cool. You can't use Pylance with it etc. VSCode degrades to being notepad.exe. MSFT uses Cursor for product research and then rolls out the learnings into Copilot because only Copilot supports all of "Visual Studio Code" features that users expect (and this is by design)
