By their very nature, most service providers collect data for
multiple parties via a centralized service.  The data is
only separated after the protocol stream is parsed, which is
fairly immediate.  Debugging will occur on both sides of that
separation process and is permitted by each controller as part
of the typical service contract.

Industry participants have not provided technical evidence that historical linkable data would be essential for debugging unlinkable practices, and at any rate, I'm not comfortable with any provision that allows continuous linkable data collection.

I believe the current language for the debug permitted use already implicitly includes this, but that we can make it explicit in non-normative language.
