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.
