I don't want that, however.  Please give up this notion that you can
tell anybody else what they might want.  You need to show how that
alternative mro is useful, and for some purpose other than arguing
against the current design of super.

I wrote a lot more, but I need to cool down before sending it, if at
all.  But here's the general problem with all of your "what ifs":

Multiple inheritance is not a general specific, it does not solve all
problems.  "Some people, when faced with a problem, immediately think:
'I know, I'll use multiple inheritance!'  Now they have multiple
problems."

If multiple inheritance causes you problems, maybe it's absolutely the
wrong design pattern for your program.  So *you* need to show us
examples of real code for real problems[1] where there's a clear use
for multiple inheritance (or at least an API which documents that one
right way to use it is multiple inheritance) and still super() with
the C3 mro messes you up.


Footnotes: 
[1]  They don't have to be big problems or proprietary code; computing
Fibonacci sequences will do, if you can find a way to make MI relevant
to that task.
