The IETF has a somewhat different composition than the current IPP group.
Different sets of people will naturally identify different needs.
For those who attended the IPP BOF at the last IETF, the IETF's 
concern over inventing a new protocol instead of adapting lpr should not
be surprising.  Several IETF participants have expressed similar concerns
to me personally.    I've tried to convince those people that lpr is 
basically broken and non-extensible, but some of them are still concerned
about compatibility.  Hence the charter requirement.

lpr is of course not the only protocol for which compatibility is
desirable, nor is it necessarily the most important one overall;
it's just one particular need that several IETF people identified.  
The mapping need not be a standard (it can be an Informational document) 
but it does need to be documented.  Documents describing mappings 
to other protocols would also be welcome, and it would be wonderful 
to have example source code to accompany that documentation.

I assume you meant this as analogy rather than an accusation.

I think it's fair to say that there is suspicion both on the
part of some members of IPP to IETF, and of some members of IETF
toward IPP.  The best way to address this problem is to get the
two groups working together.

Nor do I think there are any.  It's just a matter of documenting
how it is done.
