On a second thought, it's not that great idea as it seemed. What if e.g. mail directories (like /var/mail/<user>) are automounted the same way? So in the end I still believe that (with fixed -f option) admin written script which generates a list of mountpoints and runs "quota -f <mountpoints>" is the best way. hm .. so If I understand correctly: you will not include this feature in new release ?
