I'd probably change it more to be "do it when explicitly asked to,
or whenever the inode is being updated for other reasons and an
atime update could be made" - that is "unless instructed, don't do
inode updates that update nothing but the atime", or IOW, "atime
updates are not urgent and not required but are not prohibited".
That is, the purpose of noatime is to reduce I/O, not to hide the fact
that files are being accessed (same with nodevmtime).
