Is there anything to /remove/ a query parameter?

I'd say this is outside the scope of add_query_params().

As for the duplicate handling, I've implemented a threefold strategy that should address all use cases raised before:

def add_query_params(*args, **kwargs): """ add_query_parms(url, [allow_dups, [args_dict, [separator]]], **kwargs)

Appends query parameters to an URL and returns the result.

:param url: the URL to update, a string.
:param allow_dups: if
    * True: plainly append new parameters, allowing all duplicates
      (default),
    * False: disallow duplicates in values and regroup keys so that
      different values for the same key are adjacent,
    * None: disallow duplicates in keys -- each key can have a single
      value and later values override the value (like dict.update()).
:param args_dict: optional dictionary of parameters, default is {}.
:param separator: either ';' or '&', the separator between key-value
    pairs, default is '&'.
:param kwargs: parameters as keyword arguments.

:return: original URL with updated query parameters or the original URL
    unchanged if no parameters given.
