There's way too much bikeshedding in this thread (not picking on you
specifically). I think the originally proposed API is fine, except it
should *not* reject duplicates. To add duplicates you'd just call it
multiple times, e.g. add_query_params(add_query_params(url, a='x'),
a='y'). It's a pretty minor use case anyways.
