Anticipated spec changes

Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).

Hello everyone,

After we shipped iterator helpers, we discovered a web incompatibility in websites using airgap.js (a product from transcend.io). As a result, we unship iterator helpers to fix the issue. After getting consensus on the proposed solution, now we are ready to ship iterator helpers again. Please let us know if you have any questions or concerns.

Best regards,
Rezvan
