That's the point. Even if you use hakchis uninstall function:I think he refers to possible traces or evidence of hacking, even when on stock kernel?
Yes, the kernel will look like untouched. And yes, maybe even all the other files and directories will be original again. And of course, the system will behave exactly as in its original state. That's what Cluster says and I believe him.
But: There will be a lot of unused space in the (NAND) memory, as it is on every original device. And within this memory there will be traces of the contents of the former files - even if these have been deleted. It is a more than common technique in digital forensics to look at this. A very simple approach would be to scan the entire (unused) memory for the string "hakchi" since it is a foder name used by the mod.
It is a theoretical discussion, and most users won't (should) care. Even I don't expect Nintendo to do this. But it would be absolutely no problem for them to prove a mod in case they have a reason to do so.
So anyone who cares should be aware that you will never get a 100% original state back unless you made a full NAND backup before your first mod which has been restored afterwards.
