Sure, but the issue is not just figuring out which package to load. We have to either branch the packages or create several different packages which have overlapping code in them. Either way, this becomes increasingly complex from a development point of view (testing, merging, backporting, copying code between packages, and so on). As I said, it may be unavoidable, but I'm not looking forward to it.
