Yeah, I agree it is a bit of a niche. However, there are other code
paths that might want only the size and not the type (e.g., we already
know the object is a blob, but want to know size before deciding how to
handle diff). But in general, I doubt the performance impact is a big
deal there. It's only measurable when you're doing millions of objects.
