I think your choice of keys is better than in project-switch-commands.
Maybe these keys should be copied to project-switch-commands, so it will to be
in sync with project-prefix-map?

Or is it possible to use project-prefix-map directly in project-switch-commands?
For example, by using set-transient-map?
