 See it as the opposite: an additional way for a PG to "base" *not* to
 define the standard universal variant, but instead only declare it.
 Concretely, in `muniversal-1.0.tcl`:

 {{{
 if {[variant_isset universal]} {
    # muniveral variant code
 }
 base_define_complete_universal_variant   no
 }}}

 somewhere in `$prefix/libexec/macports/lib`:

 {{{
 if {[tbool base_define_complete_universal_variant]} {
     variant universal description {} {
         # universal variant code
     }
 } else {
     # only declare the universal variant so ports can use it
     variant universal description {} {}
 }
 }}}

 > but would of course require all ports that use the portgroup to be
 visited to adapt them to the changes.

 Or you could use the PortGroup as a transparent means to tell "base" to
 use the muniversal approach.
