That probably was the reason when package managers were invented. I don't think it makes sense today, especially when we do have some package managers downloading in parallel (like dnf as I mentioned). That means at least some distros believe their infrastructure can handle it. As for volunteer servers, if a particular server can't handle >N connections, it can drop them. No reason to gimp clients instead. And specifically in openSUSE's case, nobody has put forth server bandwidth / limits as a reason not to parallelize downloads. [1][2][3] It's just not been done because nobody (including myself) has cared enough to figure out how to do it.
