Comment:

 `libsoup` has now been updated as well, with legacy bindings provided by
 `libsoup-2.4`. The same approach was used vis-a-vis the other ports, with
 the latter being pulled in automatically.

 Longer-term, we'll update the new versions with their upstream designation
 - such as `libsoup-3.0`, `glibmm-2.68`, etc - and stop pulling in the
 legacy bindings. That will require that we also update all dependents, to
 pull in their required version.

 @dbevans and I will collaborate on all of this, as time allows. Definitely
 making progress though!
