Accessibility of methods in FieldMap for getting Groups from default to public

Can the accessiblity of the follwing methods in FieldMap class be changed from Default to Public ?

/* package */
List<Group> getGroups(int field) {
List<Group> groupList = groups.get(field);
if (groupList == null)

{ groupList = new ArrayList<Group>(); groups.put(field, groupList); }

return groupList;
}

int getGroupCount(int tag)

{ return getGroups(tag).size(); }

Map<Integer,List<Group>> getGroups()

{ return groups; }

It will be really helpful in order to iterate through the groups in the message generically.
