Interesting question. I've been hunting moose for well over 35 years (Deer as well) and have never even considered baiting them - I bait the crap out of my deer stand, but the thinking there is - you want to get the deer used to the fact that if they come "here" they will get an easy meal - that takes a bit of time to develop.
I do use scents now for moose (used to just "go moose hunting" back in the 70's with Rem Core Lokt bullets (didn't need Mono's or uber-bonded boat-tails, and you wore a red checked jacket and rubber boots (no blaze orange and gortex)- and your moose tag included a bear tag, because bears were just "pests" back then), both liquid and the smoke sticks when "sitting a watch", but also do a lot of stalking for moose - they are not as skiddish as deer so if you find some fresh tracks you can track them down and they will let you get pretty close before they even really take notice.
But maybe part of it is that my deer stand is 40 minutes from home - can get out and "tend it" pretty much year round if I want.
Where I hunt moose is a 10 hour drive followed by a 5 hour train ride - so not going up a week or two before the opener to "put out some feed" to maybe get them coming to a particular spot. Maybe if my circumstances were different (??)
