lgtm, with a question on the return of SyncManager::getSyncStatus

[tbenr]

let's put this LOG back to debug too

teku/beacon/sync/src/main/java/tech/pegasys/teku/beacon/sync/forward/multipeer/MultipeerCommonAncestorFinder.java

Lines 71 to 72 in 3d0dd71

	return findCommonAncestor(latestFinalizedSlot, targetChain)
	.thenPeek(ancestor -> LOG.info("Found common ancestor at slot {}", ancestor));

I added an experimental change to the PR, adding more info taken from the BatchSync.
It is not good in the current form but we can play with it until we find the final form.
