I could imagine that for small systems/workstations you might have some files that want access time, and others that wanted NOATIME -- it seems the new flag lets you choose on a file-by-file bases. That's why I asked. I imagine it won't help on any well-administered production server since they'd probably mount the whole filesystem that way; but might help a bit on out-of-the-box-default-config benchmarks done by naive users who don't tweak filesystem settings. Don't know if we'd care about such an audience or not.
