withNx in nx monorepo does pull in the entire nx structure since 3.9.8

I used to have this setup in next.config.ts:

import { composePlugins, withNx } from "@nx/next"

const plugins = [
  // Add more Next.js plugins to this list if needed.
  withNx,
]

export default composePlugins(...plugins)(nextConfig)

That works in 3.9.7, but no longer in 3.9.8. I dropped withNx to make this work. Not sure what withNx does.
