Quicklisp does actually aim to help in this regard. Project archives and
metadata are kept long-term, with the aim of going back to previous sets
of working configurations as needed. That includes swank and
slime. (Of course, there's no guarantee that the old software works with
the new Lisp implementations, and Quicklisp currently doesn't make any
effort to archive e.g. SBCL snapshots...)

The API to take advantage of this long-term stability hasn't been
exposed, yet.
