As @mikkelfj says, I believe there was a concern about state at the server
for connections that have not yet been established, if it receives only
part of a ClientHello. I don't think this is a debilitating concern
however. I would like to air this for a little while though ... I remember
us using the assumption that the ClientHello is a single packet a few
times, and I'm not sure if we did document them all.
