I've updated the default URLs (on a new install) to handle this, though I can't actually generate many URLs other than what would match the first one (youtube.com/watch?v={$id}) or the "short" link.
Updating the URLs on upgrade is actually rather difficult as people can and do modify them (and some add-ons do as well). Changes such as this can trigger errors. Given that I'm not actually seeing these URLs in the wild (any more?), I'm not sure it's necessary as part of the upgrade, though I could be persuaded if their use is common.
