   I'd like to echo an observation I write to the [other 
PR](https://github.com/apache/iceberg/pull/14387#discussion_r2452531286): the 
runtime of this test suite seems long, introducing test dimensions could make 
it worse. I'd be careful here and only cover different format version where it 
matters and in fact adds to the test coverage.
   
   Another thing: @adawrapub I saw that some of the tests aren't run with the 
new params (like testTableWithManyPartitionStatisticFile). If I'm not mistaken 
these are the ones that create the test table not by the @BeforeEach 
functionality but by calling `createMetastoreTable`.
    - Just noting, that these tests won't pick up the format-version param. 
    - Another comment that when I ran them parameterized I found that they 
aren't idempotent: the run for the first param succeeded, but the runs after 
failed. Probably some cleanup after the first run also cleaned up something 
needed by the runs after, because when I changed the table name to be unique 
between runs (e.g. adding the test param value to the name) then all the runs 
succeeded.
