I think changing this in the back-branches is a super-bad idea. If you
want, you can add a comment in the back-branches saying "oops, we
shipped a field that isn't used for anything", but changing the struct
definition is very likely to make 0 people happy and >0 people
unhappy. On the other hand, changing this in master is a good idea and
you should go ahead and do that before this creates any more
confusion.
