Fwiw, my touring partners this year include 4 splitboarders and a guy recovering from an ACL injury whose transition involves putting on a knee brace. My wife takes both skis and pack off when at lap changes. It's mostly not a time/minutes thing, I just don't like to force myself to mess with more stuff than necessary. (edit: also, in the conditions I most want goggles in, they are most likely to get snow in them when I'm taking them on/off) But I'm more than happy to stop at the top/bottom and take in the scenery, take a picture, whatever. For some context, of the 41 days in the bc I have this season, probably 3/4 are early am before work, and probably more than half are solo. So on a lot of days going faster = more skiing, and if I'm solo, I can optimize that a lot.
I've been carrying not just the goggles I never use but also a repair kit, first aid kit, stove/propane, 2 person shelter, 800 fill down puffy, skin wax, etc etc all season. Doesn't mean I take them all out every time I rip skins. Not changing what's on my head (and hands and chest etc) once I get out there is just a happy-path optimization for me personally; do whatever works for you. It's also a personality thing, if I can find a way to not have to mess with things more than once, that's what I'll do. I don't like taking my shoes on and off either, drives my wife nuts
I'm not trying to convey "never stop and breathe or take any wasted action and I will glare at you if you take your pack off at transitions," just "I sympathize greatly with people who would rather not use a helmet than have to fidget with it; here's the compromise I made, which seems at least marginally safer than not using it."
