This assumption is wrong at the root.

Simply put: Gentoo does not run the last-mile edge of distfile distribution.

$ dig @ns1.gentoo.org +noall +answer distfiles.gentoo.org IN A
distfiles.gentoo.org.   7200    IN      A       64.50.233.100
distfiles.gentoo.org.   7200    IN      A       140.211.166.134

ftp-osl.osuosl.org.
ftp-nyc.osuosl.org.
ftp-chi.osuosl.org.

And historically also TDS & another provider.

Plus all of the regional mirrors that don't even have .gentoo.org
hostnames.

I would like to replace the legacy http://distfiles.gentoo.org/
functionality with a redirection service, at which point you could have
partial data, but it answers a very different question than Goose.
