Hello, and sorry for the lack of a timely response on this one.
I believe the store team is already working on a mechanism to simplify the workflow in this case.
At the same time, I really hope we don’t get a feature that will do a completely automatic release to any channel besides edge, with the following rationale: we cannot really claim something is stable before anyone has looked into it at all.
There are several things that can go wrong during a build process, and given the nature of snaps once the snap is released it gets automatically refreshed into everybody’s system, so it’s important that the final result built gets a chance to be looked at before it is widely distributed.
The workflow I hope we get to eventually is that the build service will build the stable snap and make it available for installation by the developers. Then, after someone has looked into it, just click a button saying “Yep, that looks good to go into everybody’s systems!”.
