I'd be interested to know what these cases are, because I can't think
of any. Plugins already have the $wpdb connection available to them,
why would they ever need to make another connection to the same DB?

You're missing my point. $wpdb is first created every time anybody
loads a page on the website. PHP is not persistent across hits. So
forcing every single hit to the site to always get a new DB link is a
huge amount of overhead for next to no gain.
