Is my understanding correct that __proto__/setPrototypeOf are still
required if you want to do things like that with instances of
Function? Or did Function's constructor finally get patched to let you
set a prototype?

nope, if you have a dict and you use __proto__ nothing should happen,
that's why Object.setPrototypeOf is suggested: it's more powerful + it does
not show up in getOwnPropertyNames as '__proto__' does so it's shenanigans
and errors prone.
__proto__ is not even more elegant than

You are correct, lots of
that's why it's the preferred choice ... otherwise we keep promoting and
trapping developers behind a broken pattern.
If we keep saying just use `__proto__` code won't ever migrate but it's
been discussed that in some case `__proto__` is a very problematic keyword.
just for topic and documentation sake ...

this works in Firefox since quite a while, and probably some other engine
that supports
I was surprised to discover that in chrome at least this is valid:
var obj = {};
obj.__proto__ = undefined;
but this throws
Object.setPrototypeOf(obj, undefined);
Is it intended?
