Yes, the default should remain to update the atime, but there may
well be people who don't mind losing a little POSIX conformance in
return for better performance. Me for example.

This patch could also be useful for people who spin down their disk
drives after a certain period of inactivity. At the moment the
disk gets spun up again to write the atime every time some daemon
(like cron) wakes up and reads a file that was in the cache anyway.
So it will probably be popular with laptop owners.

I'll be using this patch, and I hope it makes it into 2.1.
