For the record, in order to remove this annotation:

• We'll have to decide what to do of the corresponding programmatic API, because it relies on this annotation to represent the passed options. Important note: this API wasn't deprecated as part of HSEARCH-2310 Closed , so removing it in a minor seems a bit... harsh?
• If we want to use only configuration options (and not the programmatic API), we may have to add new options to set the provided ID field name, the field bridge, etc
