Doesn't that result in "cannot resolve ambiguous function call" failures?
If you try to pass an oid directly, as a value of type oid, you should get "function is not unique". But if you cast a string or numeric value to the appropriate reg* type for the object you are using, it should work fine.
I have functions which reset object permissions on all objects in a specified schema back to the default state as if they had been freshly created which rely on this. They work very well, and allow me to have a privilege-granting script for each project which always fully resets all the privileges back to a known state.
