Yeah, but I wonder, what's the benefit of streaming here at all.

The only benefit I see would be scenarios with quite large files /
streams where we already can do something useful with just parts of it.

Images usually are only useful when already downloaded completely. At
that you dont need streaming anymore, as you already have everything
in memory or on-disk.
