Since before there was no explicit form submission algorithm every browser
implemented it as it liked and so did intranet developers (who of course
developed their websites accordingly to their company business rules [including
which browser to use]).

So, if this submission algorithm affects only HTML5 websites (and it does not)
then there would be no problem at all, but since it affects _every_ HTML
implementation it does retroactively break existing sites.

I don't see any logic into the current implementation (as i said, why image
input elements do not send their value and other input elements do? is there a
logic reason that we don't know?) so this seems more like an error/bad-choice
in the algorithm than something that exists for a reason.

Also, previous HTML 4 documentation
(http://www.w3.org/TR/html401/interact/forms.html#h-17.4) says nothing at all
(or at least i can't find it) about the fact that the name-value pair should
not be sent and although HTML 4 specs are outdated this implementation adds a
(illogic) rule that removes the name-value pair even from pre-HTML5
implementations.

So the question is: is there a logic behind removing the name-value pair? Is
there a reason? If not then why shouldn't this be considered a retroactive rule
that breaks existing sites?
