I'm easy here. I sure do not want to slow down progress of this spec.
I think it makes sense but well...
(I find UTIs rather sexy since they have inheritance which media-types do not have).

Hallvord, it should be called media-types btw, or?

On Mac it depends on the applications whose descriptor has been loaded (by the Finder I think, it might also be those that have been launched once). At least an application download and launch can cause a change in the supported media-types of the OS.

If anyone is willing to consider trusted web-sites (and MSIE already does?) then it is worth included.
