Antoine Pitrou commented on ARROW-14999:
----------------------------------------

IIRC, the reason for ARROW-7173 is that implementations historically chose 
different field names, so we had to do that for proper interoperation. It 
doesn't seem to be necessary for list types.

> [C++] List types with different field names are not equal

> When comparing map types, the names of the fields are ignored. This was 
> introduced in ARROW-7173.
> However for list types, they are not ignored. For example,
> {code:python}
> In [6]: l1 = pa.list_(pa.field("val", pa.int64()))
> In [7]: l2 = pa.list_(pa.int64())
> In [8]: l1
> Out[8]: ListType(list<val: int64>)
> In [9]: l2
> Out[9]: ListType(list<item: int64>)
> In [10]: l1 == l2
> Out[10]: False
> {code}
> Should we make list type comparison ignore field names too?
