Well, downstream projects certainly COULD, but the question is, have they? For example, CXF uses ASM, but doesn't have it listed in the features.xml. Karaf has just always provided a version it could use. CXF is likely different than a lot of apps though in that it has a VERY broad range for ASM (can use 2.x - 4.x) and can thus use whatever version is there whereas most apps are likely locked to either 3.x or 4.x. Basically, 2.3 might not load a project whereas 2.2.x will if that project has a dependency on ASM 3.x but never declared it. Yes, technically a bug in that projects features.xml. I agree with that. But it is something we should likely note in the release notes.
