If you would have written 1994, no one would have questioned anything. But 1993 httpd didn't even run on Solaris yet and the Linux network stack was beta at best. Gopher was also more common than HTTP at that time which makes people wonder if you're just a poser. The RFC you cite is the first result when you Google IP over Ethernet. You should've better googled when it was supported by Linux which was indeed 1994. You only support this doubt because because you get immediately offended.
