The optimistic sync spec was updated since the LC based optsync module was introduced. It is no longer necessary to wait for the justified checkpoint to have execution enabled; instead, any block is okay to be optimistically imported to the EL client, as long as its parent block has execution enabled. Complex syncing logic has been removed, and the LC optsync module will now follow gossip directly, reducing the latency when using this module. Note that because this is now based on gossip instead of using sync manager / request manager, that individual blocks may be missed. However, EL clients should recover from this by fetching missing blocks themselves.
