I think (would have to check the code) that 2.x peers do not consider
the MORE bit on identities.

In fact the frame that 2.0 suggests sending to discover a 1.0 peer is
invalid according to the 1.0 protocol, where the 'final' byte must be
%01, not %7f.

ZMTP/1.0 would benefit from being corrected to document the way the
2.2 codebase actually works.
