See #520 Our framework-level integrations (e.g. [Rails](https://github.com/DataDog/dd-trace-rb/blob/08c823edb60f61f75c1d96876d599bbf47dd6c62/lib/datadog/tracing/contrib/rails/framework.rb) or [Sinatra](https://github.com/DataDog/dd-trace-rb/blob/08c823edb60f61f75c1d96876d599bbf47dd6c62/lib/datadog/tracing/contrib/sinatra/framework.rb)) can perform changes to the configuration of their sub-parts' integrations. For example, the Rails integration configures the Rack integration: https://github.com/DataDog/dd-trace-rb/blob/08c823edb60f61f75c1d96876d599bbf47dd6c62/lib/datadog/tracing/contrib/rails/framework.rb#L66-L71 This...
