Repro steps

I got the issue when running the react hooks plugin that seems to use the babel plugin under the hood now.

The issue is here:
https://github.com/facebook/react/blame/ea0c17b0952e2b866a1f0dd4b5ac28c7df9d8518/compiler/packages/babel-plugin-react-compiler/src/Validation/ValidateUseMemo.ts#L110-L123

It seems to be new with latest version of the eslint plugin (v7), but not sure why without a proper changelog.

IMO an async function is just a function returning a promise, and there's no reason a promise isn't a valid value to be memoized.

How often does this bug happen?

Every time

What version of React are you using?

19.2

What version of React Compiler are you using?

none

Reproduce the warning using the linked React Playground example, then inspect compiler/packages/babel-plugin-react-compiler/src/Validation/ValidateUseMemo.ts at lines 110-123. Determine whether async functions should be accepted by useMemo or whether this behavior needs configuration, and verify that the chosen behavior is covered by the relevant compiler or plugin tests.
