// queries with the same number will return the same descriptor.
// * If the user no longer uses an unknown EnumValueDescriptor,
// it will be gc-ed since we only hold a weak reference to it in
// the map. The key in the corresponding map entry will also be
// gc-ed as the only strong reference to it is in the descriptor
// which is just gc-ed. With the key being gone WeakHashMap will
// then remove the whole entry. This way unknown descriptors will
// be freed automatically and we don't need to do anything to
