Or remove entries (or temporarily blacklist > the built-one ins), etc? While this should be enough for now (the introspection MSR list is very small, and we're probably the only consumers), that's indeed the way for the future, I think. We should have a set-like container of unique elements that can grow and shrink and can be searched quickly, and add / remove MSRs we're interested in there. The CR write events bitmap approach clearly doesn't work, as there are too many MSRs to be able to select them all with a bitmap in the future.
