I really don't see why. When the user clicks "print" he wants to print 
what he sees. He might want a slightly different layout (thus print 
stylesheets) but why would he want different content altogether?

Let's remove a way to do these things then (especially amending the 
style attribute, which is semantically extremely dubious, and very bad 
for accessibility).

I really don't see why @media print { } is not good enough. It is, after 
all, what it was designed for.
