Hmm this design feels weird to me. What arguments would realistically be passed through this?  In the underlying issue, the OP needs to send `timestamp_as_object=True` to `.to_pandas`, to control how the data is formatted as a dataframe.
If it is not a real concern, I can close this PR. I am +1 on this, the most important is probably types_mapper, which is a real PITA that this is not possible at the moment Something like `read_pandas(to_pandas_kwargs=...)`  feels strange to me from an API perspective, and has the downside of really intertwining the APIs of the libraries. If we later decide to change the allowable `to_pandas_kwargs` or pyarrow decides to change their API it would be quite messy

Why not just encourage users to call `pa.parquet.read_table` in such a case directly? Would updating the documentation be sufficient in your opinion? This pull request is stale because it has been open for thirty days with no activity. Please [update](https://pandas.pydata.org/pandas-docs/stable/development/contributing.html#updating-your-pull-request) and respond to this comment if you're still interested in working on this. @WillAyd ? Sure I think documenting this is a reasonable approach Thanks for the pull request, but it appears to have gone stale. If interested in continuing, please merge in the main branch, address any review comments and/or failing tests, and we can reopen.
