Full Ack.

I have just used yesterday the following line for our IoT device.

echo '55' |curl -v --max-time 5 telnet://...:port

which isn't possible with ftp(s)/http(s)/...

I can also use socat or install telnet but it was a nice feature to have
it in curl.

As I don't know how much work the maintaining of this protocol is or how
much it blocks for the further future of the curl/libcurl project.

I just wanted to raise a hand and tell you that there is a use case
where this protocol is useful.

When the decision is to remove this protocol, It's also fine for me.

I assume that such a discussion will happen for some other protocols
when it's planned to remove it from this fantastic library ;-)
