Despite this expectation in SotW, due to a quirk in the protocol we can actually enable one of our most important optimizations. XDS types form a tree, with CDS and LDS the root of the tree for Envoy. For root types, we *must* always generate the full set of resources - missing resources are treated as deletions.
