Followings should be changed to coerce to object dtype.

Coerce to tz-naive / UTC

Slice (__getitem__) resets tz BUG/API: Make consistent API for tz-aware and tz-naive ops #11351
.loc assignment coerces to naive BUG: .loc assignment of datetime with tz is coercing to naive #11365
GroupBy.first coerces to naive Taking first row from each group in groupby sometimes strips tzinfo #10668
DataFrame.combine_first DataFrame combine_first() loses timezone information for datetime columns #10567
Index creation API: DatetimeIndex creation with mixed tz timestamps #11488 -> changed to be Index(dtype=object) (BUG/API: Index creation with different tz coerces DatetimeIndex #11696)

Raises TypeError / ValueError

DatetimeIndex.union raises TypeError BUG/API: Make consistent API for tz-aware and tz-naive ops #11351

Bug

Series.append raises AttributeError BUG: Series.append with DatetimeBlock and DatetimeTZBlock raises AttributeError #11455
concat raises IndexError Inconsistent concat behavior between datetime64[ns] and tz-aware version in 0.17.1 #11693
replace bug in Series.replace with timezone-aware datetime columns #11792
