Indeed. Namespaces partition the set of identifiers in such a way that
the same identifier can be bound in different places to different
meanings, and that you can refer to each of the different meanings of an
identifier either by using their namespace prefix(es), or by importing one
of the meanings of an identifier ("using" in C++, "import" in Java).
Elisp has a single namespace, and this does not change with shorthands.
So indeed, as you write, shorthands are better characterized as a
workaround for the lack of namespaces. Nonetheless, they provide one of
the features of namespaces, namely that you can import subsets of the
possible identifiers of the single namespace and access them through a
shorter name.

This is not at all what namespaces are about. This is aliasing.
