I still think this is an acceptable footgun (?) to have. The expressiveness of downloading an image tag with a domain included outweighs potential miscommunication issues.

For example, if you're on a team and you have documentation containing commands, but your docker config is outdated, you can accidentally pull from docker's global public registry.

A welcome change IMO would be removing global registries entirely, since it just makes it easier to tell where your image is coming from (but I severely doubt docker would ever consider this since it makes it fractionally easier to use their services)
