I don't understand the reason for using a registration system rather than just importing names from a module.

You mentioned wanting to globally change the executor class being used by a program without having to make changes throughout. Registering a different class under the same name would be one way to do that, but you could achieve the same thing just by assigning to a name in a module.

In other words, instead of inventing your own mechanism for managing a namespace, just use a module as your namespace.
