Because that's what the specification says.

It's like you wanted to visit "google.com" and your browser said:
"Ok, I will see if www.google.com exists and if so, show you 
https://www.google.com (not https://google.com), but if there is no
www. subdomain I will try showing https://google.com directly"†


sequoia also goes to the openpgpkey.domain.tld url first. The
difference with gnupg is in their treatment of errors.







† NB: this is a fictitious example. While browsers do have some
heuristics if the provided domain fails, like prepending a "www." or
making a web search, I know of no browser doing that *before* . Using a
www. for web addresses is just a convention. Although we could have
ended in this situation if things had developed slightly different.
