Which is a good thing, because...?

Oh, I see - that answers all questions.  "Software has detected an issue",
so of course an issue it is.

... except that the result is not objectively better by any real
criteria.  It's not more readable, it conveys _less_ information
to reader (the fact that calls differ only by the last argument
had been visually obvious already, and logics used to be easier
to see), it (obviously) does not generate better (or different)
code.  What the hell is the point?

May I politely inquire what makes you so determined to avoid any
not-entirely-mechanical activity?
