Comment 2 for bug 319991

The symlink is required for backward compat for mail clients which use stock_mail-priority-high as the icon for "important" e-mails. If evolution has been updated to use emblem-important instead, then this particular link can probably be patched out (though, I don't know if balsa, claws, or anything else uses it as well).

Ideally, I'd like to see the idea of emblems and tags separated, and this portion of the UI removed from nautilus. I'd like to have the ability for users to set tags on files, but I don't think we should be using those tags to display additional icons overlaid on the file icons in nautilus/dolphin/whatever. The tags should be used for search and filtering, allowing the user to more easily find files, while emblems are used to display status information (such as readonly, unwritable, shared, etc..) to the user, as icon overlays. I think working to move in this direction is the best way forward.
