It is unfortunate that when pruning is activated, the NODE_NETWORK bit is
cleared.  This means that supporting SPV clients means running full nodes
without pruning.  OTOH, a pruning node could support SPV clients that sync
more often than once every few days, especially if it stores a few GB of
block data.
