When we used this, we used the first directory to be the env, so it looked like.

    /prod/...
    /stage/...
    /dev/...
    /feature-xyz/...

It's not elegant, but it made for really simple scripts that let us prepend /${env} to every key to access what we needed.

And of course, each service per env had different access tokens so apps in the stage env couldn't read prod keys.
