this already happened to some extent. the “blessed” way to develop github is in vscode (from ms), using codespaces (from ms), running on azure (from ms). vim/emacs users can use the terminal (although the codespace and port forwarding, at first, had to be done via vscode exclusively) but your entire toolstack needs to be installed each time you launch a new one.
collaborating with anyone at ms already meant you were using teams to some extent.
