Enabling Picture-in-Picture (PiP) in WKWebView

I'm working on a web browser App that's distributed via the App Store. This app renders web pages using WKWebView.

Our users are requesting a way for us to allow them to play videos in Picture in Picture. After some investigation, we noticed that in order to allow PiP videos in our browser in the sandboxed environment, we need to add the com.apple.PIPAgent entitlement under the com.apple.security.temporary-exception.mach-lookup.global-name option.

We tried to submit our app with this entitlement, but unfortunately, we were rejected:

Guideline 2.4.50) - Performance
We've determined that one or more temporary entitlement exceptions requested for this app are not appropriate and will not be granted:
com.apple.security.temporary-exception.mach-lookup.global-name
com.apple.P|PAgent

We would like to have access to this entitlement so we can offer PiP to our users. We already created a radar about this as well: FB13814428

Additionally, we have another radar (FB13557716) regarding allowing the usage of a private flag _allowsPictureInPictureMediaPlayback, which would also be required to enable us to use PiP.

Is there any way in which we can currently enable PiP? Would opening a TSI help here?

Since Apple isn't responding to TSIs this week, but will be looking at developer forums I was wondering if it would be possible to get some response on this query. It'd be great to be able to offer PiP to users.
