Review Comment:
my concern was around providing context on "why" this lambda is here and
implemented the way it is. [This
comment](https://github.com/apache/iceberg-python/pull/1457/files#diff-ddd56fc195d637dbe64ed201cc875ec9cb5d67f243eabc438ccca4238a8508a9R825-R826)
refers to [this
function](https://github.com/apache/iceberg-python/blob/3b580111760f0749922ea593dbe0b1d602952438/pyiceberg/schema.py#L1303-L1307)
which is also used in the write path
to me, it make sense to use the same function to show that we're doing the
same thing as what the underlying system is doing
