Comment (by adamsilverstein):

 > Wondering it is would be cleaner to have a filter like this.

 $new_ext, $mime_type ) );`

 flexible.

 @spacedmonkey This might be a little cleaner or more flexible, however we
 loose some (existing) functionality.
 * If the requested type is not supported by the server, fall back to the
 default mime type.
 * Normalize the $filename to a wp path (although this would still run
 before the filter).

 The current approach also feels a little easier to use from a developer
 perspective. Leaving as is for now!
