It's not silly, I can see where this might be very useful; but noatime
is applied at the vfs level and not at the filesystem level, so putting
the flag in the filesystem superblock on disk and propagating that back
up to the vfs at mount time might require a bit of trickiness to get
right & do cleanly, I'm not sure.  I'll give it some thought.

It may be simpler & quicker to just tell your auto-mount framework to
mount certain devices, or labels, or uuids, or $WHATEVER with noatime if
you can?  Of course that configuration is local to a single machine, and
doesn't travel with the drive...
