I imagine it is because different implementations are probably going to
want to implement URL handling slightly differently. For instance we
were discussing having the Unity8 QPA plugin grab the Mir surface ID
and pass it along to URL Dispatcher so that we can properly display
errors or application choosing dialogs on the right surface in Unity8.
Also the way that URLs are registered is significantly different
depending on implementation.

I would suggest that we could include the "snapd-xdg-open" tool when
someone specifies the "unity7" interface.
