According to the docs the default behavior tries to avoid removing imports that could have side effects, and providing this -a will remove even those imports. I think that for a default configuration it makes more sense to omit the -a. I like the defaults to avoid potentially logic-changing formats, and it's easier to add the -a back in your own config using prepend_args than it is to remove -a from the list of arguments.
