I guess this might call for a blueprint? It should be discussed with the kernel team also. Can you please write a blueprint specification, and then post on devel-discuss or kernel-team?

I for one would welcome this change.

This was discussed briefly a while ago, and decided to use relatime by default, but I'm not sure if there was some installer component which lacked support.
