True, it's not 1-1 in the mathematical sense (bijective), only surjective.
However, it is 1-1 for all code points which have a name assigned.

I don't any advantage of using these over plain \uXXXX codes.

Yes, but they are official aliases, not official code point names :-)

The .aliases() function would have to return a list, not a single
name, so a parameter would cause the return type to change, which
is not a good idea.

A new function also makes the origin of these names clear to the
