Again, we're already changing the ipp-versions-supported and the IPP
header to have 2.x version numbers. Doing a separate spec that is
literally 8 pages of boilerplate and 1 page of real content seems like
a lot of overhead for this!

Keep in mind that CUPS already supports 3 out of the 4 formats I've
proposed. However, I'd argue that we need at least one printer
vendor to implement it as well...
Also, given the mess we have today, I think we really (really!) need
to do interop testing and come up with a standard test suite that
vendors can use to self-validate. (CUPS already has much of this in
its "make check" automated tests to validate its IPP/1.1 conformance)

IPP/2.x with no required document formats is no better than IPP/1.1.

True. The question is, who will upgrade to IPP/2.0 if there is no
compelling reason to do so?
