That's exactly what it is, but doing that is *required* by the telnet protocol
under certain circumstances.

It's actually the other way around... the old things like VModem handled the
telnet protocol and the door game didn't have to worry about it.  Many modern
doors however are being passed the socket itself and now the door needs to
support the telnet protocol and every doorkit author needs to understand the
telnet protocol instead of it being handled by the VModem and only the person
who is setting out to write a telnet package needs to deal with the telnet
protocol.

Having the door "speak" telnet when it is passed a socket also ends up causing
issues when the BBS uses SSH instead of telnet because SSH is an 8-bit-clean
protocol, so all of the telnet things that a door has to do, it has to not do
for SSH.

Basically it's "cause door is being passed a raw socket and has to telnet
protocol itself" instead of the much more sane "telnet server does telnet,
door doesn't care".
