Packagers should generally only be looking at tagged releases in the upstream repository, though -- not every commit.
Personally I'm a fan of zero touch where I as a developer submit my code repo to app store like play store, apple app store, flathub or something and they just build it using a standard definition that the store defines and make it available on the store. Kind of feels like a lot of effort for every distro to look at every change in every application...
It wouldn't be that often, though. And maybe they would actually love to have such heartbeat. I would love to hear a packager on that.
