What are the typical uses of the Data Collector?

[The Data Collector](https://learn.microsoft.com/en-us/sql/relational-databases/data-collection/data-collection?view=sql-server-ver16) is the single most obscure SQL Server concept that I know of. I have never even seen it _mentioned_ in a professional or educational context, never mind _used_. I don't even think that it has a tag on this website, although I have made my best guesses. Yet, its [support in dbatools](https://docs.dbatools.io/Copy-DbaDataCollector) is a strong sign that it must have some value. I have read the documentation for the Data Collector with an open mind, but I simply cannot fathom a use case for it. What are some typical use cases in supported (i.e. 2012+) versions of SQL Server?
