Comment (by TobiasBg):

 Thanks for the background on this, @lenasterg!

 I'm not sure why the login form, needs to pass empty arguments here, but I
 assume that it would be "too late" to change this anyways, for backwards
 compatibility reasons (as the filter hooks that run during the request)
 might be overriding the calls to perform some custom authentication.
 Your proposed changes do make sense, therefore.

 It might be worth updating the function's docblock then as well, to
 clarify that `null` is a possible parameter value/type.
