The fix that no one asked for 😄 props to @berkinanik for bring this to my attention over in eslint-plugin-jest-dom.

Weirdly ESLint doesn't seem to think some of the result syntax before this is invalid (namely in no-done-callback which'd give ((), ) => {}), but didn't feel like digging into that further right now.

Best practice for fixers are to avoid doing stylistic fixes since that should be enforced by another rule (which will be automatically fixed if possible), to help keep fixes as small as possible.
