Yonik Seeley commented on SOLR-2272:

Sorry, I can't entertain this nonsense.
Lucene and Solr merged as equal projects.  The domain of neither project shrunk.  There is
no "right place" for this code.  People could have done the work with their lucene hat on
or their solr hat on.

The history behind this particular patch is that it was for a customer using Solr - and I
scoped the time based on that.

It's simply preposterous that an improvement to Solr be blocked because some might want a
lucene-usable module too.  It's just as preposterous to block a lucene improvement because
solr can't use it yet.  If someone wants to do something for lucene users, fine.  But that
currently has no bearing on this patch.
