We can only hope their new package system will contain something that allows the programmer to chose their own database. I want to use Couchbase and Elasticsearch. I can't see why any other document store couldn't do the same job as Mongo. Don't get me wrong, I'm ok with Mongo (but it's not for me) but can't we make at least some choice???

You can make your choice! The problem for a lot of people: you need to write a real-time adapter if you want it to be efficient and performant. We have implemented Redis adapter, for example: https://www.youtube.com/watch?v=-Vnb8tjnE3k
