I did wonder if that one provocative statement would even be noticed :-)

You make a good argument. I see the functional point of a top cut. Helps prevent condiment excursions. Less likely to break in half. BUT, it's just so much bread. And the hotdog does want to pop out.

I'm unaware of any baseball park or hotdog stand where top-cut buns are sold. This is clearly an established best practice. Hotdog consumers have made an aesthetic choice here.

Baseball Park: Fenway[1]

Hotdog Stand: Not uncommon in Rhode Island (and probably other parts of New England). I've seen Saugys[2] sold from food trucks in side-cut buns but it's the exception rather than the rule.

As a non-American, I was unaware that side-cut hotdog buns even existed.

Then again, in Australia, the standard container for a "sausage sizzle" (grilled sausage) is a slice of plain white bread.
