[jbosscache-dev] Region activation of a root node

I noticed that o.j.c.statetransfer.VersionedTestBase#testLoadEntireStateAfterStart does region activation on a root node. Region activation triggers partial state transfer but since we are activating root node partial state transfer mechanism rejects this requests. Do we allow region activation on a root node (i.e cache.getRegion(Fqn.ROOT, true).activate())?
