Also, to this day we don't have any TLS library support in the platform,
which also is subject to debate of which crypto-library to use (and
there's also the question whether to use OpenSSL via FFI or a native TLS
reimpl). So the platform-included `HTTP` package is not even able to
access `https://` URLs which is quite sad, as this also holds back
`cabal-install`'s ability to access `https://`-only repositories.
