I hear you.
But I'm not seeing many alternatives, unless we start taking write faults on them unnecessarily. Do we care? Probably not really.
So we certainly *could* make ramfs/tmpfs claim they do dirty accounting, but just having a no-op writeback. Without that, they'd need something really special in the file time updates.
Personally, I don't really see anybody really caring one way or the other, but who knows..
