[Cob] is the final word in on rebar in cob walls?

My brother-in-law has used rebar but he coated the rebar in cement first
as the cob sticks quite nicely to the cement, compared to the rebar
alone.

I know, I know, this has been discussed before, but it seems I can never
find someone who will state with experience about a yes or no for rebar
used
to reinforce cob walls. Anyone willing?
In my small experience of building alongside experts, we used urbanite
with spider-y old rebar hanging off it in mid wall, just to gain height
and remove that crap from the landfill. It's not a total reinforcement,
but it's moving towards it.
The negatives usually listed are that the rebar pulls water out of the
'breathing' wall, starts rusting, gathering more water, etc.
