In the context of the linked article "velocity" is defined to be "Short and focused release cycles, aligned personpower, leveraging the community effectively". I think VS Code exhibits this value.
If you're interested in a reliably-quick-to-start editor, and prefer the Emacs ecosystem, consider https://www.gnu.org/software/zile/ . It's built for that purpose.
Amongst other things, it lists different values that each tool prioritizes, and how "Core values are self-reinforcing. They attract like-minded people, who will then defend them."
Emacs: Extensibility, Freedom, Introspectability, Keyboard centrism, Stability, Text centrism.
That is, even if VS Code achieves technical parity with Emacs (wrt introspectibility/extensibility), its community might not prioritize using VS Code for things beyond editing code.
Or maybe it will. These things are difficult to predict!
