configure({ onUndeclaredKey: 'delete' }) seems to allow extra properties through.
Thank you for all you do. I’m going to try to replace zod for Arktype at work this year. Wish me luck.

And maybe the docs should call that out, as it’s two files in the example but not clear why

Ohh okay. Gotcha. That makes sense anyway in a real app. But doesn’t play well with just playing around.

Adding comment to object key
I'm fairly certain this is impossible. Typescript doesn't give type authors any APIs to make sure these survive transformations.

using an const array as a source for a string literal union
nice. Thank you.

Nice. So the '===' just infers the type from what follows it?

v10 useQueries does not return a stable reference
Ended up with 
function useMemoizedResultData<T>(results: { data: T }[]): T[] {
  const previousResultData = useRef<T[]>([])
  const resultData = results.map((result) => result.data)

  if (areArraysEqual(previousResultData.current, resultData)) {
    return previousResultData.current
  }

  previousResultData.current = resultData
  return resultData
}

/** Returns true when `a` and `b` are arrays with perfectly identical contents. */
function areArraysEqual(a?: unknown[], b?: unknown[]): boolean {
  if (a === b) return true
  if (a?.length !== b?.length) return false
  return !!a?.every((item, i) => item === b?.[i])
}
function useMemoizedResultData<T>(results: { data: T }[]): T[] {
  const previousResultData = useRef<T[]>([])
  const resultData = results.map((result) => result.data)

  if (areArraysEqual(previousResultData.current, resultData)) {
    return previousResultData.current
  }

  previousResultData.current = resultData
  return resultData
}

/** Returns true when `a` and `b` are arrays with perfectly identical contents. */
function areArraysEqual(a?: unknown[], b?: unknown[]): boolean {
  if (a === b) return true
  if (a?.length !== b?.length) return false
  return !!a?.every((item, i) => item === b?.[i])
}
Which feels like a bit of a hack, but it seems to work.

I guess trpc v11 and tanstack query v5 fix this with the combine option. Maybe I should focus on being able to upgrade instead

This does work, which means the data prop is stable 
  const foo = useMemo(() => {
    console.log('memo recreated')
    return results.map((result) => result.data?.id)
  }, [results[0]?.data])
  const foo = useMemo(() => {
    console.log('memo recreated')
    return results.map((result) => result.data?.id)
  }, [results[0]?.data])
but I'm not seeing how to get a stable array of the data objects themselves
