They are all possible. Whether is makes sense is in the eye of the beholder :-)
Scenarios 1 and 3 are both changing the BSN (bundle symbolic name) of an installed bundle. Scenario 2 is about adding a BSN. This is probably more common as people start to take advantage of R4 function. Scenario 1 is possible of a bundle is refactored into a set of bundles, but in that case it is more likely the original BSN will still be needs as a facade bundle to combine the refactored bundles.

Whilst I agree some of them are a bit theoretical, I'd like to get your opinions on how to deal with them (best practices if you wish). These issues are related to the Bundle-SymbolicName. When talking about Bundle-SymbolicName, the spec (3.5.2) says: The installation of a bundle with a Bundle-SymbolicName and Bundle-Version identical to an existing bundle must fail. Furthermore, on bundle validity the spec (3.11) says (amongst other things): Updating a bundle to a bundle that has the same symbolic name and version as another installed bundle [causes a bundle to fail]. Scenario 1: Updating an R4 bundle with symbolic name A to one with symbolic name B. Provided B (with the same version) does not exist yet, this should not fail, although for me it is strange to change the symbolic name in an update. Scenario 2: Updating an R3 bundle to an R4 bundle. Provided the symbolic name and version of the R4 bundle does not fail, this should be possible. Scenario 3: Updating an R4 bundle to an R3 bundle. This should be possible, but might break dependencies that are using the symbolic name. Any comments on this?
