I think it makes sense to enhance the hook system to make sure hook is
run when it is installed. But if it cannot be done then "update cache"
should be run in post_install() of desktop-file-utils similar to what
gtk-update-icon-cache package does [1].

I agree that xdg-utils uses desktop mime cache and it should depend on
desktop-file-utils.
