I've just tried this, and the most touched files are also the most irrelevant or boring files (auto generated, entry-point of the service etc.) in my tests.
I just tried it too and it basically just flagged a handful of 1500+ line files which probably ought to be broken up eventually but arent causing any serious problems.
Yeah same thing happens with lockfiles and CI configs. You end up filtering out half the list before it tells you anything useful.
