Joris Van den Bossche commented on ARROW-9997:
----------------------------------------------
Personnally, I think moving away from the mapping API is quite a usability
regression. Would it be a possibility to still provide that as the default, but
have a alternative way to get a field by position?
(in a similar way, Table and Schema also work like that, they raise when
getting a field by name and the name is duplicated, but you still can get a
field by name)
> [Python] StructScalar.as_py() fails if the type has duplicate field names

> {{StructScalar}} currently extends an abstract Mapping interface. Since the
> type allows duplicate field names we cannot provide that API.
