Understood what you're saying, but sorry - disagree; and dark vs. light ambient visibility while changing cells wasn't what I was getting at.
imho battery carriers for small-cell AA/AAA lights are inconvenient, awkward due to the size & form factor. With small cells it's easier-faster just to drop them in (think not only flashlights, but also e.g. cameras).
fwiw I also believe this applies to larger size cells too. Forgive me
I have a thing against battery carriers, unless they're 'integrally' well engineered and otherwise robust, failure-proof. Fenix has come closest there on a few of their high end designs. Carriers are just one additional separate/loosely/tenuously tethered component, separate from the main light body, which has failure/loss/damage-outside-the-light potential. And, one more thing to fumble with (in any situation, irrespective of ambient light/weather conditions).
