I don't think it all that fragile.  All the back ends will have
unique names.  If the user doesn't specify a pstore= argument we
keep the current "first past the post" method. If they do, then they
can choose which one, or specify pstore=none (or even pstore=not-bloody-likely,
since any not matching string will disable) to turn it off altogether.
