We need to improve Release Notes for EAP 7.1.0. In Unsupported Features in Messaging (ActiveMQ Artemis) chapter there is:
Colocated HA topology configured using replication-colocated/shared-store-colocated

It's insufficient as it implies that colocated HA topology is not supported which is not correct.

It should be improved in this way:

Colocated HA topology is supported as described in Configuring Messaging Guide - <provide link to [1]> 
- but configuring colocated HA topology using replication-colocated/shared-store-colocated is unsupported/deprecated
