Nice RFC, thank you :-)
in my experience RFC 1925 item 6a is the final root cause behind
about 90% of all bugs and RFC 1925 item 5 is also a final root cause
behind about 90% of all bugs so about 81% of all bugs have both together
as final root cause (I really mean that seriously - to some extent)
i.e. indirection plus complexity is the "highway to hell" ;-)
I still believe it is possible to create good abstractions, though
it is not simple. IPP is an example of good abstraction for printer.
Fortunately, IPP-scan specification exist, and it provides
a good abstraction for scanner.
I think whatever will be done the outcome would be OK as long as you
keep Open Printing (in particular Till Kamppeter) involved, cf.

Kind Regards
Johannes Meixner
