This feels like one of those things where you're saying something that is maybe technically correct, so you can feel smart, but has no bearing on reality. A store near me sells capers in a short-and-fat glass jar (which even a large spoon can fit in easily). I've been able to leave those in the fridge just fine for 6 months with no noticeable change in quality... just like the tall-and-narrow glass jars. Based on my personal experience of these two jar shapes, any difference in spoilage-rate is imperceptible. What are you basing your "spoil faster" on?
