At the moment, I don’t have a solid real-world example to provide. This work is still in an exploratory stage.

We shouldn't be in the business of "if you build it, they will come". Unless there is a concrete use case now, I would not be adding anything.

My entire workflow for what I created in the tracing system was "I have a need, I will implement it". The "need" came first. I then wrote code to satisfy that need. It should not be the other way around.
