I don't know, why would a user write 'defvaralias' to set a user
variable?  They're users, completely unpredictable!  ;)

That would work too.  I made a couple of other suggestions in
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=5950#42

Maybe we should add something like

    (defun defvaralias! (new-alias base-variable &optional docstring)
      (set new-alias (symbol-value base-variable))
      (defvaralias new-alias base-variable docstring))

Which you could use to tell Emacs not to care about losing the original
value of NEW-ALIAS.
