This is an important point that people seem to be overlooking. The
complexity and maintenance burden of PEP 580 should be compared to the
status-quo. The existing code is complicated, yet nobody seems to find
that a problem. But when PEP 580 makes changes to that complicated code
(and documents some of the existing complexity), it's suddenly the fault
of PEP 580 that the code is complicated.
I also wonder if there is a psychological difference simply because this
is a PEP and not an issue on bugs.python.org. That might give the
impression that it's a more serious thing somehow. Previous
optimizations (https://bugs.python.org/issue26110 for example) were not
done in a PEP and nobody ever mentioned that the extra complexity might
be a problem.
Finally, in some ways, my PEP would actually be a simplification because
it replaces several special cases by one general protocol. Admittedly,
the general protocol that I propose is more complicated than each
existing special case individually but the overall complexity might
