Review Comment:
From the Parquet end, the CRS is never absent (or: if omitted, we know it's
lon/lat). From the GeoArrow end, an omitted CRS means "the producer does not
know", the verbage of which comes from GeoParquet and basically follows what a
CRS of `None` is in GeoPandas. All to say that I think this part is correct
(but you're right that it's annoying to handle for everybody).
