No it doesn't. The problem you described most likely happens because
client request body carrying files contains encapsulation as well as form
fields. This inflates request body up to certain amount.

In fact upload module is a small hack as well.

But you can take a look at (not officially published yet) branch 2.1 of
upload module and see how discarding and unzip modules are implemented:


Although filters in this branch of upload module are not chainable yet, I
plan to implement it. And if you make any filter based on current
implementation in between, it will be very easy to integrate such
additional filter.
