This always seemed trivial to me to do with:

This has different semantics from Promise.allSettled, right? In
particular, it effectively treats rejected promises as resolved with the
rejection value, forgetting the fact that they were rejected.
Promise.allSettled, on the other hand, preserves information about the
state.
I think you can still polyfill it, using something like:
Promise.all(promises.map(p => p.then(
v => { { status: "fulfilled", value: v } },
e => { { status: "rejected", reason: e } }));
though I think this might create more temporary Promises than allSettled
does...
