Good points but think they're really not that essential, especially if 
it's only about one language and just the use of it.

Considering the capabilities of multiple inheritance and some situations 
where single inheritance don't apply and needs workarounds - like when 
you make a class that needs to inherits a class from an external library 
but also needs to inherit its natural parent class whereas you had no 
choice but to just include the contents of the natural parent class to 
it - I believe that's not always true.

Perhaps but please consider the example situations I gave. I doubt that 
solutions could always be done without redundancy either by code or by 
work while not sacrificing consistency among classes and not using 
workarounds.
