See the editorial note at the end of §3:

  << RB: OSI Layer 5 session analog?  This is obviously intended for
   TCP "sessions" which aren't distinct from Layer 4, but is this also
   applicable to DNS-o-DTLS, or DNS over UDP with an EDNS cookie - I
   think probably "yes" for the former, but "no" for the latter.  I'm
   wondering whether "session" is even the right term to be using

So, yes, our start point is TCP, but it might apply to other protocols
that give the effect of a single end-to-end connection.  That's TBD.
