I think this proposal is unlikely to gain traction. But if it were, in a
Lisp context colon (:) would make more sense IMHO, as it is used in Common
Lisp to separate the namespace ("package", in CL-speak) from the symbol
name. That would make easier to adapt to CL-style namespaces, if they were
implemented in Emacs some day (which I think won't ever happen, if previous
discussions on the subject are to be believed).
