That depends on what you mean by "semantics." :D

In the case of podcasts/vlogs, I'd say yes. The media file is primary.

Uh, this is already possible with podcasting/vlogging.

Yeah. Media revolution is off topic. :D

Eh, don't think so. The use case for enclosures (at least for me) has  
been for the UA to download and queue the media file up for later

I don't think so. I think there's still a place for enclosures in  
html. Just like, thought we can send HTML, RTF or PDF (*shudder*),  
attachments are still useful.
