Sounds exactly like "edge" to me ;)

This perfectly fits the channels of snappy.

Same thing is true. Anyway, if the package is uninstallable we will not
be able to build and push the os-snap.

We would end up with it in the *edge* channel of the os-snap, but we
would not promote that revision to the stable channel :)

Edge is allowed to break. That's the point of it. Alpha, beta, RC, next
type channels would be curated but might of course still break. Stable
will be highly curated and very unlikely to break.
