Ah, this is the key point of my proposal. Stability for my purposes

I did consider that parts of this proposal might be easier in snaps,
which would be a bit more like you describe.
I tried to limit to items that we could test for a 6 month period of time.

Then we have monthly releases, I specifically didn't want to do that.
Obviously it's something that could be considered instead though.
