The only "simple" use of super() is in the single inheritance
case. But that's also the case where it gains you the least
over an explicit inherited method call.
If you have multiple inheritance, and

My guess is 100%.
Pretty much all modern interpreters of any language execute some form of
byte-code or another. The bad old days where interpreters repeatedly parsed

If super() is confusing, it is because *inheritance* is confusing, and that

In my book, "receiving bug fixes" means it's still supported.

Presumably Nuitka does not depend on any byte code at all. Jython uses
JVM byte codes. Iron Python uses .net VM bytecodes.
While CPython's byte codes do take their form in part becaus

As a beginner I'd try to code using Python idioms rather than writing
Python using BASIC idioms.

Yes, that would be one of the exceptions to the rule, but
not because the rule is unsound, but because Python
