Loading data with timestamps that have timezones result in error

When loading data that has a timestamp associated, the following error occurs:

duckdb.InvalidInputException: Invalid Input Error: timestamp field value "2019-01-10 05:21:23 -0300" has a timestamp that is not UTC
Use the TIMESTAMPTZ type with the ICU extension loaded to handle non-UTC timestamps. at line 1 in column "creationdate"

I believe this behavior is the one mentioned in the comment: https://github.com/jwills/target-duckdb/blob/ea8341defd9ea20a25c24f2f2ef9e2e638d7b9b8/target_duckdb/db_sync.py#L30-L32

Opening the issue to raise the discussion:

Isn't the TIMESTAMPTZ type more general? In other words, wouldn't it always default to UTC0 if not specified, and support the TZ if specified?
If the general case isn't enough, what could be the better way to conditionally map the type?
