I don't know that filters are intended to be used in if blocks like that.
It would seem more natural to have a has_req_field method in your form and
write:
{% if form.has_req_field %}
(Yes, then each form you want to do this with has to have this method, but
there are Python ways to enable that without actually having to duplicate
the code in each form.)
