Review Comment:
Hm, thinking aloud: `existing_data_behavior` controls how the dataset will
handle data that already exists. If I implement a unique way of writing parquet
files when using the new API in `wrtie_to_dataset` I will also have to set
`existing_data_behavior` to be `overwrite_or_ignore`. That will then make
trouble when exposing the same parameter in
https://issues.apache.org/jira/browse/ARROW-15757.
I could do a check if the parameter is specified or not. But am not sure if
there will be additional complications ..
