Given the choice between only "atime" and "noatime" I'd agree with you.
Heck, I use it myself.  But "relatime" seems to combine the best of both
worlds.  It currently just suffers from mount not supporting it in any
relevant distro.
And here is a completely untested patch to enable it by default.  Ingo,
can you see how good this fares compared to "atime" and
"noatime,nodiratime"?
Umm, no f**king way.  atime selection is 100% policy and belongs into
userspace.  Add to that the problem that we can't actually re-enable
atimes because of the way the vfs-level mount flags API is designed.
Instead of doing such a fugly kernel patch just talk to the handfull
of distributions that matter to update their defaults.
