Why are you assuming there's any client-side validation code involved?

The URI is not displayed in the url bar unless the new page is shown. 
If the URI results in a file download, it won't be shown in the URL bar.

They don't, of course.  But that's not even relevant in the "generate a 
download based on form input" case.

I think you're assuming people care about SEO for the file to be 
downloaded....  In many cases they don't.

My point was that these techniques, as far as I can tell, impose a cost 
on the user, unless I'm completely misunderstanding how they work...

I agree that if you fix up URIs on form submit on client side that cost 
is pretty small in the common case.

These two were clear, yes.
