What would you say are planned to be the primary selling points over VSCode?
From the other parts of the thread: Performance, maybe better collaboration?
Despite VSCode being an Electron app, I've never had any performance issues with it - really, it's a great example of how Electron can be done right.
On collaboration, I'm not sure what they might add that isn't already covered by GitHub/GitLab/AzDo etc. Again being honest, "collaboration" sounds like a weak Open Source pitch to VCs. I'd be interested in some details though, incase there is something truly novel here.
