the way I read, it, lubos was suggesting something more like "if you want to 
install support for $feature, click here" instead of "oh, you don't have 
$feature, good luck finding and installing it on your own!"

magic can be good when it's implemented right :) and I'm sure the existing 
complaint dialogs already come with don't-ask-again checkboxes where 
appropriate.
