> Also Rails, why didn't you pull this out into a separate plugin/gem like you have with everything else?

1) Who did most of the extractions previously were Rails developers, not someone from the Rails Core Team;

2) Most plugins extracted from Rails are not even in github.com/rails anymore, other people forked and are now maintained them. So we recommend you to do the same if you care about memoize this much;
