   > baking in schema coercion into the parquet reader at this level
   
   Oh I think I understand. My initial impression was that 
[`ArrowReaderOptions::with_schema`](https://github.com/apache/arrow-rs/pull/5939)
 is the intended mechanism for overriding the Parquet level schema. So the 
nuance is that in the original issue the goal was to supply a hint to a Parquet 
with missing type hints, whereas in my case I want to override an 
already-hinted Parquet schema, thus somewhat abusing/overloading this mechanism?
   
   I guess then that #6735 could also provide a solution to this problem 
(albeit with more effort). Let me take a look at it.
