Description

Inferring the schema of a DataFrame from a list of dictionaries feels natural for PySpark users, and also mirrors basic functionality in Pandas.

This is currently possible in PySpark but comes with a deprecation warning. We should un-deprecate this behavior if there are no deeper reasons to discourage users from this API, beyond wanting to push them to use Row.
