I actually prefer the first suggestion of just having a file-global bool.
If and when we get other checks that need to be done selectively [e.g. "snprintf into a too short buffer produces a prefix of the full string", which also came up during this discussion but was ultimately kept] depending on the %<whatever> being exercised, we can add a "u32 nocheck" with a bunch of bits saying what to elide.
Not insisting either way, just my $0.02.
