Not really true. I've found bugs triggering opps using cpufreq-bench.
http://marc.info/?l=linux-pm&m=138165517321579&w=2

and i hope you learned from that experience and run this tool when
making changes to the core.

There is an old writeup of cpufreq-bench here:
https://lwn.net/Articles/339862/

and the code itself is in the mainline tree, tools/power/cpupower/bench
