is this bug?

[Vasilisc]

In snapcraft.yaml I request
   plugs: [network, network-bind, x11, home, unity7, pulseaudio, 
mount-observe, gsettings, locale-control]

After upload TuxGuitar in Ubuntu Store I see

$ snap list
Name          Version               Rev  Developer  Notes
tuxguitar-vs  1.3.2-snap1           1    vs         -
ubuntu-core   16.04+20160531.11-56  122  canonical  -


$ snap interfaces
Slot                 Plug
:gsettings           tuxguitar-vs
:home                tuxguitar-vs
:network             tuxguitar-vs
:network-bind        tuxguitar-vs
:pulseaudio          tuxguitar-vs
:unity7              tuxguitar-vs
:x11                 tuxguitar-vs
-                    tuxguitar-vs:locale-control
-                    tuxguitar-vs:mount-observe

Not autoconnect
locale-control
mount-observe

User must manually in CLI connect mount-observe for example?
