Well, that's sorta my concern. I mean, right now we've got people
saying "what the heck is a replica identity?". But, if the logical
decoding stuff becomes popular, as I hope it will, that's going to be
an important thing for people to adjust, and the information needs to
be present in a clear and easily-understood way. I haven't studied
the current code in detail so maybe it's fine. I just want to make
sure we're not giving it second-class treatment solely on the basis
that it's new and people aren't using it yet.
