Like @chipaca I use both yq (and jq) a lot on Ubuntu Core systems and would be very sad if the snaps were transitioned to only classic support as then I can’t use it with Core anymore and would probably have to resort to maintaining a fork of the snap that is strict so I can use it on my Core systems.
@mikefarah if you’re sure that you want classic support, would you consider only publishing classic revisions of the yq snap in a classic channel much like how @popey recommended @Lin-Buo-Ren do for the nano snap? Then in the normal stable channel you could still publish the current version of yq that is using strict confinement so we can use it on Ubuntu Core still.
