Comment 3 for bug 1869505

a developer knows what he has added to plugs as he knows that the content snap will be published by him as well, see the snapcraft file there is no stage-packages, stage-snaps property anywhere.

still snapcraft need to install cnotent snap, 240Mb in my case.

I don't think content snaps entry need a check by snapcraft. If still this is just a check, whats the need to install it ??
