@MartinK: Its somewhat easier for all applications/libs that are a part of the distribution (Fedora, for example). In our case, we are these third-party providers that have to follow the main distribution and rebuild accordingly.

In this particular case, it would be handy to have ability to specify package built for specific SFOS version (so, I could provide Mapbox GL QML versions for 3.0.1, 3.0.3, and so on) at OpenRepos. Currently, only through OBS I can do it in some kind of sane way. But then, its users who would have to subscribe to the correct channel.
