Description

The CategoricalBlock was removed in pandas (https://github.com/pandas-dev/pandas/pull/40527), which breaks the nightly tests.

I will argue in pandas to add it back on the short term (https://github.com/pandas-dev/pandas/issues/40226#issuecomment-804903010), but we should still remove the direct use of those Block subclasses in pyarrow.
