Have you done any relative performance metrics on the two versions?
Versioncache was (almost certainly) intended as a performance
optimisation, but that was a long time ago, and it's certainly possible
that it's no longer necessary. But we'd need evidence of a lack of
decrease in performance before we remove it.
Common operations like buglists, showing bugs and longlist would need to
be tested.
