IMO it's more reasonable to use only DKIM and encourage others to do the same.
Well, even DKIM is not "the magic solution" either and it does not address the same issues as SPF does - it just breaks for other things. SPF authenticates (well, more or less) the sending network/server, while DKIM authenticates the content - but it can be replayed if you happen to have a valid signature for a mail and it fails for mailinglists like swinog, because adding a footer to the mail breaks the signature...
