Embed Google Forms iFrame in Posts

I saw a few Idea’s already on allowing iframe and embeding but I wanted to provided my usecase to this series of requests.

I am revamping my Knowledge base categories and along the way I also want to launch with a form to request new Knowledge Base content.   A form is the best route.  However on testing it works in the back end but does not post as the iframe html gets stripped.

If there is another way to do this, let me know but allowing iframe is the quickest route to get this done in a timely manner.
