I have thousands of people using it daily in dozens of different installations
so keen to avoid any significant changes/loss.

I have no intention of removing it but as Robert has pointed out in a couple of
issues there is huge scope for improvement which we cannot ignore. I'll make
sure to document any changes.

- the fact it caches 'rewrittenQuery' in the QUERY itself, this means the Query
is keeping IndexSearcher-dependent state in the Query: this is broken.
- the static similarity, which at the moment must extend TFIDFSimilarity (does
not work with other scoring systems)

Good points. The cached rewrittenQuery seems like an easy fix (albeit a change
that should be documented). I see your comments in code about averaging out
statistics. That seems like a bigger issue. Moving away from a static
similarity seems like its doable at this stage. Is the agnostic scoring model
support a showstopper?

> In LUCENE-3271, I moved the 'good' queries from the queries contrib to new
> destinations (primarily the queries module). The remnants now need to find
> their home. As suggested in LUCENE-3271, these classes are not bad per se,
> just odd. So lets create a sandbox contrib that they and other 'odd' contrib
> classes can go to. We can then decide their fate at another time.
