LGTM - we have tested this for a while on holesky-rescue branch and it was very useful to speed up our sync times + retrieving more details about our connected peers, see discord thread for more details

if we ever return FAR_BEHIND, then lodestar nodes will most likely disconnect peers that want to sync from us which is not great for the network. Should we remove FAR_BEHIND completely? or add more info for it
if we delete FAR_BEHIND enum then there is only 2 options: CLOSE_TO_US and FAR_AHEAD. At synced time, this function will always return CLOSE_TO_US. Hence the main usage for this function is for syncing time
please add all of these to the function description for later reference

if you have time would be good to add a panel somewhere that uses the bool

seems like we need to update tests here I leave this up to you @wemeetagain to make sure it's done correctly, I don't think we need this in 1.28, so there is no rush |

once Fusaka goes live we should update this to use fulu.Metadata, or just if-else based on clock slot but we need the type first #7774
