I think encoding the security origin in the URL allows the UAs to do the
security origin check in place, without routing through other authority to
get the origin information that might cause the check taking long time to
finish.

If we worry about showing the double schemes in the URL, we can transform
the origin encoded in the URL by using base64 or other escaping algorithm.
