But you want them still logged as errors?

I would say for always logging any exceptions that are thrown except
in corner cases where you can check before trying if that operation
will fail.

You can print the stack trace from the handler with traceback.format_exc()

That will reraise the exception that is being handled, useful when you
want to cleanup something, but then let the exception keep flowing as
usual.
