I'd argue that the only requirements are high bullet density, complex bullet patterns, high difficulty, and a focus on precise dodging between bullets. Larger hitboxes can have equally precise dodging requirements and similarly complex patterns, small hitboxes are the genre standard but not a requirement.

The whole game is full of screens full of bullets with complex patterns and tight dodges, I don't know why you're being so uptight about it. Nothing about the genre is being degraded.
