Once there is upstream support for the OpenVINO plugins in GIMP 3.0, we’ll migrate people there, but for now this new track will allow us to publish somewhere.
There is no button to delete tracks because that is not a supported action.
The main reason being that devices on the wild can still be tracking that channel.
I see the channel was already closed (you can check in the metrics tab the % of clients that are still tracking it)
Maybe the UI of snapcraft list-tracks could be improved and only show non-closed tracks?
Just an idea, will try to raise it in our next cross team meeting
