Apart from migration concerns, is anything in Lucene 6 allowing us

The best one seems to be the new encoding technique for numerics -
also mentioned as breaking API - is fabulously more efficient: smaller
in terms of index space, much faster to query and also somewhat more
efficient at indexing time: faster and less intensive on the JVM heap.

Not least it supports multi-dimension numeric fields, so stuff like
Spatial get a double win.
The Query API now include Guillaume's patches to make our life easier
to transform them to ES, and they've been working more on making
queries immutable. Filters were not removed but are based on the
immutable queries, it seems all like sensible cleanup to me.
The Lucene mailing list is talking already about what should be
included in Lucene 7 so I'm having the impression of a bit of a more
aggressive version increase pace.. Nobody can tell of course: maybe it
will take the somewhat usual amount of time but it seems possible the
project is ramping up on dev speed.
