-1 on adding api

there is no reason to support this as it's not round trippable - nor is Series a common format out there. just add a doc recipe. @jreback ah okay Im happy to dump this if not worthwhile, would you mind taking a look / commenting on the issue [here](https://github.com/pandas-dev/pandas/issues/54638)? Your point about not being round trippable was brought up and debated Closing as this feature probably needs more discussion These kinds of inconsistencies in the pandas API and friggin' infuriating. Users don't particularly distinguish between a series and dataframe in working code. For example, the result of doing pd.concat on some selection from a dataframe might be a dataframe or a series depending on how many columns match the criteria. Borking a downstream serialisation because your frame turned into a series is not fun. Arguing that to_parquet on a series is not round-trippable so shouldn't be supported is childish arrogance.
