Well, the protocol says you can do it, but it would likely require
significant work to make clients deal with it sanely.

Also, the part of the protocol document Heikki is quoting is for the
legacy "simple query" mode.  We deliberately designed this behavior
*out* of the extended query mode.  So for example you couldn't use
out-of-line parameters with such a feature, unless there's a protocol
redesign.
