We have several cases where we need to define mapping for fields at package level, atm we have to define them under each data stream, same goes for ecs fields like message or error.message etc.
Would be great to provide a mapping at package level or even higher when it comes to ecs fields.

Same situation for pipelines, in some cases same processing of fields is required in all data streams for an integration, atm we have to define the shared pipeline at each data stream level.
