Oh, we should definitely fix them - it's just I'm not sure people have been seeing them to be ignoring them as you mentioned above. AFAICT nobody goes on warning patrol in the selftests with any degree of frequency like happens in the main kernel, nor tunes the warning set, so they tend to build up in the older tests that aren't being updated as a matter of routine. You do sometimes get someone coming in and doing a round of cleanups but it's sporadic.
