There is a lot of effort associated with the handling and correct
validation of a redirect_uri sent to the AS as part of the front channel
authorization request, as this gets transported by user agents.

The draft-parecki-oauth-v2-1 as a replacement of RFC 6749 must make sure
redirect_uri is only sent to the AS through the back channel. This of
course requires the implementation of a new "authorization request
initiation endpoint". The draft-ietf-oauth-par-01 provides a guidance on
how to design this initiation endpoint.
