PolarSignals is specifically discussed in the linked threads, and they conclude that their approach is not good enough for perf reasons.

Curious to hear more about this. Full disclosure: I designed and implemented .eh_frame unwinding when I worked at Polar Signals.
I think I might have confused two unrelated posts. The one that references Polar Signals is this one:

So not a perf issue there, but they don't think the workflow is suitable for whole-system profiling. Perf issues were in the context of `perf` using DWARF:

Oh nice, I can't find that - can you post a link?
