Maybe, but because of a lack of convention on naming, we have namespaces.
No, we have namespaces not because we couldn't agree on naming convention, but because any naming convention without namespaces would lead to ugly code (which you call "sensible long names" but which rapidly stop being sensible if you actually try to do it).
So it would seem appropriate to have the ability to investigate a namespace to see what it contains and/or if it exists. Why? For exactly the same reasons you have class_exists(), interface_exists(), function_exists().
Classes and functions actually exist as objects in the engine. Namespaces do not. They are just parts of names. You can not instantiate a namespace, you can not call a namespace. So these reasons do not apply.
