It's the old polling problem - how you ask influences the outcome (as
I said below), and you didn't say exactly how you were going to ask
before.

Only if I was sure I wanted feedback :-)

Which do you prefer as a back compatibility policy for Lucene:
A) best effort drop-in back compatibility for minor version numbers
(e.g. v3.5 will be compatible with v3.2)
B) best effort drop-in back compatibility for the next minor version
number only, and deprecations may be removed after one minor release
(e.g. v3.3 will be compat with v3.2, but not v3.4)

In either case forward index format compatibility would be maintained
for an entire major version and the previous (e.g. v3.5 would be able
to read an index written by v2.2)
