I only wish people were so consistent and reliable. Truth is that
there is vast inconsistency in the wild.

Many people use text links to point to videos, sometimes they use
special "play button" icons to link to videos (not exactly a
thumbnail). Sometimes people link to an HTML page with the media
embedded and somtimes they just embed the media and do not use an
image to link to it. In practice relEnclosure is rarely, if ever used.

We run into all sorts of problems like this trying to parse HTML
descriptions when we aggregate feeds on FireAnt.tv.

I don't think adding additional "semantic" HTML attributes would help
much either. Often the bloggers who post with strange HTML conventions
aren't the type of people who know much about HTML. I certainly
wouldn't expect them to grok a Microformat like rel="media:thumbnail"
... but then perhaps broad acceptance is not really the goal of this
proposal anyway.
