Is this some special process for js-jquery? It is quite common that package bumps its version or soname and breaks something. We either fix the incompatibility or provide "compat" package. You can take recent update of openssl from 1.0.1 to 1.1.0 as an example. It was updated just to later introduce compat-openssl10 to not break the systems that much. How many libpng versions we have currently in Fedora and yet I don't see any Obsoletes/Provides in any of them. > And if the dependency on js-jquery is strictly versioned, an upgrade > would break such a dependency. That would be inacceptable, too. I keep js-jquery requires strictly versioned especially to know that js-jquery version was changed so I can fix my package appropriately. > Hence something would need to "Provides: js-jquery = 2.something", so no > deps would break.

I say that releasing js-jquery2 package is just "nice to have" and I have use case for it. But world will not break apart if js-jquery2 is not introduced. > Temporarily the new package would also > duplicate files found in another package or conflict with it even, > if it doesn't _replace_ the other package. Yes, and to avoid them, the proposal is to regularly bump js-jquery to version 3.x and deal with the outfall (very likely by introducing js-jquery2).
