I'm in the same situation as many, in that my first year of ownership will be up before the MM (I've done less than 1,300 miles in 7 months). I'm just going to change the oil/filter after 12 months and not reset MM. Then when the MM does eventually come up, I'll do whatever it says.
Obviously if the MM came up within a couple of months after doing the oil/filter change I wouldn't do that again, but if it had been 6 months or more, I'll probably do it again just to resync the change with the MM.
I'm not sure when MM would suggest a rear diff fluid change given low mileage, so I might do that after 2 years if nothing comes up (as I doubt I'll be anywhere near 15K by then).
