I'm not sure what you're saying. You think this term was made up by HN? Or is brand new? I can find references on the web dating from 2008 without even trying.
I'm not claiming any prior use of "Full stack developer"(TM) (haven't researched that), just that HN discussions often have a web-technology bias, where "designer" implicitly means "web designer", "low-level" means "in a VM inside a browser running on an OS running on a processor", etc.
