I'm not sure why you refer to it as "product", that's not my intent at all.

WildFly is a community OSS project, so:
 - we have several users who are stuck to whatever is compatible with WF
 - several other users stuck on older versions of ORM
 - some people eager to try latest ORM

My goal here is just to try satisfy all of them; not least it would be nice to
have the next WF version to include the Hibernate Search/Elasticsearch
integration out of the box.

Red Hat's supported products might take some of these things onboard in future,
but that's much further in time and they will definitely only take on
which have proven themselves in freely available distributions first.. so yes
in a way you're right to consider this a pre-requisite, but it's not sufficient
and it's affecting a very different timeline and audience.

So back to timelines, if I upgrade 5.6 today to use ORM 5.2 already then we'll
prevent all people using ORM 5.0 and 5.1, and also all people running on WF
from benefiting of the Elasticsearch features.

Vice-versa, if we release 5.6 with Elasticsearch support and then follow up
quickly with a very similar 5.7 which just introduces the changes to catch
up with ORM 5.2, then we have something good for everyone.
