Well, an alternative would be to move the complexity to the server. I very
much doubt that webmasters are going to create all those variations manually
anyway. And if so, it's enough to store them according a naming convention
the server understands. There are already two proposals how this could work:

  http://tools.ietf.org/html/draft-grigorik-http-client-hints-00
  http://tools.ietf.org/html/draft-snell-http-prefer-18

The browser then just needs to make sure that the right headers are set. We
would to be very careful though to not destroy the cacheability of
responses.

Of course, some form of URL templating would work as well but that probably
would become quite complex.
