Everything looks good but I'm wondering about this section, does this introduce new behavior? Should we test it?

In my testing this appeared to reduce updateStatus failures/retries. The point is that once the dv has been updated the "baseline" and mutated DV are the same

weird, syncUpdate is usually the last thing we do in the loop, how come something else runs updates after it
EDIT:
nvm I see we updateStatus after it. makes sense.
But updateStatus seems to work on a fresh copy of the DV from the cache, which should have the updates..

Good point! But the fact is that the "fresh copy" from the cache is often stale (informer didn't receive update yet). Would be better if updatestatus actually uses the copy returned by update in that case. I swear that adding this assignment was reducing errors/retries. Seems unlikely but maybe the additional time to do the assignment gives more time for the informer to update.
Anyway, worst case this assignment has no actual effect. I can remove it if you'd like but it does seem more correct to me that "dv" and "dvMutated" should be equal at that point. The fact that neither value is referenced again is kind of beside the point. That may change in the future

That is my concern; if we ever have to look at dv/dvmutated diff to compute some status transition,
this may throw us off

I don't think we should spend a lot of time wondering about hypotheticals. But what are you suggesting we do here @akalenyu?

Yeah I guess that's not very likely, I am fine with keeping it
