Currently, my workflow involves having separate "dev" and "prod" environments on railway, and I connect to dev to for local development. This work great!

A nice-to-have feature would be "locking" my prod environment such that it can't be used via the CLI like this. As I onboard new devs to my project I'm encouraging them to use this workflow, but it'd be great for peace-of-mind to be able to know no accidental selections of the wrong environment are possible.
