Comment 3 for bug 1654642

Hey Jamie, thanks for your suggestions! Using (3) seems like the best option, however we do not allow installing classic snaps on a Ubuntu Core system (all-snap) system. So I think the next best option is (1).

I pushed https://github.com/snapcore/snapd/pull/2604 with a simple interface like you described above. AIUI to full support this we will:
1. land this interface
2. add a package declaration that allows auto-connect of the "classic" snap with the "classic-dimension" interface

This should also allow using the classic snap in non-devmode (with the limitations that poking around is really limited by apparmor but it should be fine for e.g. building).
