napoleon_use_param should also affect "other parameters" section · sphinx-doc/sphinx challenge

Problem statement

Subject: napoleon_use_param should also affect "other parameters" section

Problem

Currently, napoleon always renders the Other parameters section as if napoleon_use_param was False, see source

    def _parse_other_parameters_section(self, section):
        # type: (unicode) -> List[unicode]
        return self._format_fields(_('Other Parameters'), self._consume_fields())

    def _parse_parameters_section(self, section):
        # type: (unicode) -> List[unicode]
        fields = self._consume_fields()
        if self._config.napoleon_use_param:
            return self._format_docutils_params(fields)
        else:
            return self._format_fields(_('Parameters'), fields)

whereas it would make sense that this section should follow the same formatting rules as the Parameters section.

Procedure to reproduce the problem

In [5]: print(str(sphinx.ext.napoleon.NumpyDocstring("""\ 
   ...: Parameters 
   ...: ---------- 
   ...: x : int 
   ...:  
   ...: Other parameters 
   ...: ---------------- 
   ...: y: float 
   ...: """)))                                                                                                                                                                                      
:param x:
:type x: int

:Other Parameters: **y** (*float*)

Note the difference in rendering.

Error logs / results

See above.

Expected results

:param x:
:type x: int

:Other Parameters:  // Or some other kind of heading.
:param: y
:type y: float

Alternatively another separate config value could be introduced, but that seems a bit overkill.
