Description

Multiple exports of name is always reported as an error but it's a legitimate feature disciplined by ECMASCRIPT specs.

Es:

// D.js 
const f = () => 'D::f'
export { f }

// E.js
export * from './D.js'
const f = () => 'E::f'
export { f }

Report -> import/export: Multiple exports of name 'f'.

Maybe eslint-plugin-import could give an optionable error that can ben disabled by config?

Research direction
The issue requests making the 'Multiple exports of name' error optional via a config option. The relevant rule is in the eslint plugin import repository, likely in src/rules/export.js or similar. The contributor would need to add a new option (e.g., 'allowMultipleExports') and modify the logic that reports the error. Reference issue #1704 and the StackOverflow link for context. The codebase uses JavaScript and Node.js.
