What are your arguments then ? What are your thoughts ? I use fable everyday and it is always coming up with changes on thousands of files for simple things, overall the code does the job but there is always marginal slop or unnecessary code to be addressed.

That honestly sounds like it's more about either the quality of the codebase, or the driver.

To be more concrete, the last two examples were that Fable added every time a function called utcnow in newly added Python modules, and it always ended up adding constants. I'm saying it takes a lot of effort to make sure Fable or other frontier models don't produce such marginal slop and to keep things concise.
