getpeerinfo I can see that a number of connected nodes return a
synced_blocks of -1.
Some of these have been connected for days, so:
- Is it correct to assume that these nodes are never attempting to propagate blocks around the network?
- If so, what's their purpose if they're not propagating block data around the network?
