It makes it easier though, on unplug you would otherwise need to filter what events are uncore and migrate those to another online cpu of the same nb instead of all events..
Also, what cpu on the NB receives the PMI?
Sure it can be done, just not pretty. Combine that with all the other special casing like patches 3 and 10 and one really starts to wonder if its all worth it.
