By contrast it does not reduce the safety factor for the UTXO set at
all; which most hold as a much greater concern in general; and that
isn't something you can say for a block size increase.

With respect to witness safety factor; it's only needed in the case of
strategic or malicious behavior by miners-- both concerns which
several people promoting large block size increases have not only
disregarded but portrayed as unrealistic fear-mongering. Are you
concerned about it?  In any case-- the other improvements described in
my post give me reason to believe that risks created by that
possibility will be addressable.
