Has this been run through some kind of real world performance test ? I
can imagine for instance /bin/sh's vnode is being updated a lot... Would
it be eligible to a becoming a mount option ?

I don't see any real problems with it, but perhaps people running
executables over NFS filesystems that cannot be mounted with noatime
might have an issue, like netbooting diskless machines...
