the source code still contains the key[1] while the site seems to not have any link to make it accessible publicly.
maybe bitcoin.org needs a "historical" page that can include this key alongside other historical facts and clarify that this key was created 12 years ago and may not be safe anymore. although i don't think there is anything insecure about a 1024-bit DSA key.
