Comment 2 for bug 1898622

Maciej, that PR is orthogonal, that simply prevents folks from creating non-dangerous grade images with devmode snaps in them, I have not yet proposed a fix for _dangerous_ images seeding properly with devmode snaps, though I do have a working branch locally which fixes this. It's a bit of a pain to write tests for that though so I have not proposed it yet, but hope to do so soon.
