Why ? The kernel maintains a fairly tight relationship between device numbers and mount points, so unless changes are planned there, exposing this fact doesn't seem too evil to me. (It should also work fine with devfs, if that one should ever become mainstream.)
Of course it's not nice that such a /proc/mount-devs would partially replicate information contained in /proc/mounts, but then there are good reasons for not changing /proc/mounts.
To be a little more concrete, I'd imagine to include the device number and the path, e.g. 0x302 /usr Any additional information can be retrieved in user space from /proc/mounts. The stacking can be implicit, e.g. recent mounts follow older ones.
But maybe you have a better idea ?
