I guess my question is whether Orc complied against kryo-shaded 3.x
necessarily works with kryo-shaded 4.x, because there were API and behavior
changes. Our current tests don't seem to surface any such problems, but who
knows if there's something they don't test.
I agree that our distribution won't include two versions, but the issue I'm
wondering about is whether Orc will like the one later version that it gets
bundled with.
