I'm trying to prepare for the eventual deprecation of document types in Elasticsearch, and it's not easy to nail down all conflicts. One that I'm blinking at at the moment is ['doc', '\_doc'] ...
The [Elasticsearch documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html#_schedule_for_removal_of_mapping_types) about removal of types says that
> The preferred type name is `_doc`, so that index APIs have the same path as they will have in 7.0: `PUT {index}/_doc/{id}` and `POST {index}/_doc`
On the other hand, the Logstash [6.3 Breaking Changes](https://www.elastic.co/guide/en/logstash/current/breaking-changes.html#_elasticsearch_output_changes) notes say
> The default document\_type has changed from logs to doc for consistency with Beats.
Sounds like the "consistency" should be driving in the other direction. Shouldn't both Logstash and Beats start to use `_doc` ? What is going to be best practice here?
