Presently no, and there doesn't seem to have been a lot of demand for
it, though there was at least one other request. IIRC I asked about
the motivation since normally the default sorting should do the right
thing, and I believe it was for the sake of overriding for some sites
with broken IPv6 connectivity. If you have other use cases in mind it
would be good to mention them to help document that this is a feature
that makes sense to consider adding.
