In cuDF (rapidsai/cudf#11617 (comment)), ArrowIntervalType is used when creating a cuDF column from an interval arrow array (that can original from pandas). Would it make sense to expose ArrowIntervalType and ArrowPeriodType in the public API?

any particular reason not to parametrize these like the others?

IIUC these are conceptually different than pd.ArrowType as they are pyarrow extension types (subclass pyarrow.ExtensionType) necessary convert pandas Interval & Period types to pyarrow via __arrow_array__ (? cc @jorisvandenbossche)
