It's described as a non-required field, but it's an enum (without any other listed options) and the description is vague: Used by the Application Insights system to determine what kind of flow this component was created by. This is to be set to 'Bluefield' when creating/updating a component via the REST API. - Bluefield.
My rule of thumb is don't include anything extra (KISS) that doesn't break my application, but if there's some benefit I can get out of it, I'd like to know. Thanks!
