Why tho ? Everything about the system is locked down - it's never going to be a good development machine no matter if you run electron vscode or not. It could be a decent client for stuff like web vscode.
I don't think a machine's fitness for development is correlated to how locked down it is—you can totally have a very controlled environment with gatekeeping like the current iPadOS but have well-designed tools and development environments built for it. Apple did it with macOS after all...
The only way I see this happening is if they let you run docker images/VMs. Even then it would suck for front-end. And it's such a niche use case from their perspective - I don't see this happening ever.
