I think that "once something is deployed, it's permanent". Therefore, a
mapping must be a permanent feature that can only deprecated once the
last client is removed from the internet - which i think is impossible.

It should be required. If the user experience changes from one
implementation to another implementation, users will be confused,
disturbed, and will complain.
