I was trying to claim that a user should be pretty safe if she/he is
browsing the Web with script disabled. Apparently I have likely missed
lots of 'tricks' that can be carried with CSS+HTML alone, like
@font-face + 'font-family' + <input> as suggested by Jonathan.

I am not sure I understand this...

I agree.

I can't quite believe there's a use case of applying 'text-transform' to
an input control. I guess browsers just implement this for consistency
and I don't have a strong argument otherwise, but this behavior is still
weird to me.
