Sadly this turns out not to be the case, at least if I'm reading fs/pipe.c correctly. O_NOATIME will turn off atime updates, but mtime and ctime are still modified on every pipe write, and there's no such thing as O_NOCMTIME even though the filesystem layer does have the concept internally. Which means device-backed filesystems will see write traffic just for using named pipes.
Heck of lame. Someone should fix that.
The behavior follows the standard, so it shouldn't just be changed by default without checking if anybody uses the standard behavior.

I don't speak for anybody but myself - that's enough trouble.
