As a regular user, my expectation is that the very first results from a search would be from matching the title string (possibly after trying to match the unique video id seen in the url), only afterwards would results from keyword matching and other such metadata show up.

Maybe I'm out of touch but I don't think this is an unreasonable expectation.

It's not unreasonable, and it's exactly how it used to work until Google started messing around with inserting ads into every aspect of the site (they very much want you to you click on the ad-laden videos you were NOT looking for). They changed the default and relegated it to be a search modifier.
