transformer: Warning: Spread children are not supported in React. error happens

[sapphi-red]

For input:

export default function() {
  return (
    <>
      {...[1].map((i) => <div>{i}</div>)}
    </>
  );
}

Warning: Spread children are not supported in React. error is output.
This does not happen with esbuild, swc, typescript. But the same error happens with babel.
The actual code I met is this test case in react-router.

Since this code works in other transformers but is not supposed to be supported by react, would it be possible to make the error into warning and align the output with esbuild / SWC? (Maybe the warning is not needed? I'm not sure)

Interesting, let's align and report the problem to babel? Although babel was the initial react implementation :-/

I found the discussion in babel: babel/babel#3575, babel/babel#7069.
It seems react wants to disallow it (babel/babel#7069 (comment)) and that's the reason of the error, and babel is open for adding a support for it (babel/babel#7069 (comment)).
