Eh, it doesn't matter which pilot does it. I make the walk 90% of the time, and I had a trip a year or so ago where my FO obviously noticed that I'd make the walk. I hadn't done it yet this leg and he was getting up to use the lav and said "want me to go check if there are any jumpseaters up top?" I said hell yeah thanks bro! Pretty sure the gate agent probably didn't even notice he wasn't the captain.
