In general, I wonder how much the check is useful compared to the complexity.

Yes that's the question: should traces be mandatory in some libs?
> In my opinion, opt-in for trace is more appropriate.
There was some work to add traces everywhere in few libs, so why not maintaining this state?
I don't really like adding a skip list as one more burden for future authors.
> Nonetheless, having a tool to check for tracepoint presence might still be useful for library reviewers and maintainers. And such a tool might be useful for any library, not just the few libraries suggested by this patch.
