Yonik Seeley commented on SOLR-2272:
------------------------------------

bq. Theoretically refactorings are the kinds of things that newer contributors could be helping
with but currently you have to put on a full suit 
of body armor and prepare to do "battle".

There are hypothetical scenarios which you imagine like that... and then
there are real scenarios where you discourage contributions to Solr that
do not directly benefit Lucene.
