Mark Miller commented on SOLR-2272:
-----------------------------------

And so I will argue that your veto is invalid. I don't believe you have voiced a valid technical
concern. You said that a couple committers think this could instead be integrated at the lucene
level, and that some lucene users have voiced an interest in join. IMO, neither of this are
either good reasons to revert this feature, nor valid technical reasons for a code veto.
