   This seems related to https://github.com/apache/datafusion/pull/24086 and 
https://github.com/apache/datafusion/pull/24086.
   
   In my mind what should happen is:
   - ineffective filters are never promoted to later materialization or are 
demoted from it (related to https://github.com/apache/datafusion/pull/24086)
   - io pattern lookahead prefetches all batches for the scan in one go if it's 
small/single file (related to https://github.com/apache/datafusion/pull/24086)
