No, but a lot of people are writing them in telnet prompts and through netcat pipes.
Curl and wget are nearly as ubiquitous as netcat.
The older, HTTP/1.X compatible versions maybe. What happens after the web upgrades to 2.0? How long until compatible tools make it to default installs? Even now, OSX doesn't ship with wget.
But they watch, capture and post them to mailing lists and stack overflow.
