Comment (by pbruin):
Note that there are two distinct but related ways in which objects of type
`SchemeHomset_points_abelian_variety_field` "are not groups":
- the class `SchemeHomset_points_abelian_variety_field` itself does not
inherit from `sage.groups.abelian_gps.abelian_group.AbelianGroup_class`;
- if `A` is an instance of `SchemeHomset_points_abelian_variety_field`,
the list of categories returned by `A.categories()` does not include
"Category of commutative groups" (i.e. the category obtained as
`Groups().Commutative()`), let alone "Category of groups" (i.e.
`Groups()`).
Both points are probably easy to fix, but it would also be good to have an
example of (a) concrete new feature(s) that this would introduce.
