To emphasize a core point:

    Any interesting mechanism can be modified in myriad ways.  Some of 
those are interesting.  Some of the interesting ones are actually 
useful. Only some of the useful ones are highly useful.

    Changes to multi-participant services are extremely expensive, so 
that pursuit of enhancements needs to be restricted to those changes 
that are expected to be highly useful.

    As such, any proposal should provide a basis for believing that the 
change will be highly useful AND a basis for making that assertion.

This sort of requirement is what distinguishes an engineering standards 
discussion from a more abstract intellectual/academic pursuit.  The 
latter are entirely valid, but it's important not to confuse the two.
