These types of questions are presented more as a feature request in an 
issue queue.

Based on the http://drupal.org/node/262920 issue sited below changing to

<VirtualHost *:80>
	UseCanonicalName Off

	ServerName hostname.dev
	ServerAlias hostname.com
</VirtualHost>

Should work for you.

I don't dislike your proposal maybe a combination of the two would be a 
good solution with HTTP_HOST being used first.  Work up a patch for D7 
and see where it goes.
