My initial reaction was it was not worth re-spinning for this either. But mostly based on the assumption that the user could just configure it, and at worst we could drop a note about it.
Then I saw that there would be some side affects to that based on this patch? I didn't really look closely, but from memory, I guess it would disable being able to set compound file? And you wouldn't be able to change the tiered policies settings? Or does Solr's config any given method voodoo work in this case?
Either way, I'd be fine if we didn't respin or if we did. It would still be an improvement, even if it didn't support compound, and then that can be another improvement.
