I'm not quite following why that's such a bad option?
People would get sent to the current version, sure, but there's a header
right there with a link to the prior version they actually want.
Pages being deleted might be a problem, but how would a nonexistent
"canonical" marking on a page that doesn't exist stop indexing of older
pages? Maybe we could even notice "page XYZ doesn't exist after 9.3,
so mark 9.3's version as canonical".
