Due to WASM and https://github.com/bmeck/proposal-arbitrary-module-namespace-identifiers JS can export names that are not identifiers, this generally only affects WASM though

See potential fix by using index rather than name like in https://github.com/nodejs/node/blob/255b1db9320df7b2e17a248ba4ab659d3f25853d/test/fixtures/es-module-loaders/mock-loader.mjs#L232
