Actually, I was reading this old cookbook from my grandma, and it said dried oregano is key for certain sauces because it doesn't break down as fast. Like, in a long simmer, fresh might lose its punch, but dried holds up. It made me think about how we always hear 'fresh is best' but that's not always true for every situation. Your wedding app example is spot on, because those heat lamps are brutal. I tried using fresh parsley on a buffet once and it turned into a sad green mush in like ten minutes. So yeah, dried herbs have their moment, especially when you need something to last.
