javascript should never have been considered a reliable validation tool to begin with.

It is a convenience add-on effect to have javascript "sanity check" a form before waiting for the 
round-trip confirmation from the server that inputs are wrong/incomplete/etc.

Can you get away with javascript-only form validation?  Yes.  Are you more prone to injection 
attacks?
