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.
