Hi @GeekCornerGH , after internal discussions, we decided not to go forward in merging this PR. It poses a security risk for us for now as we do not know if the site(s) are safe, and we would need to validate these and all other global domains submitted, which might take up some internal capacity. We are currently looking into ways to take this burden off the community as we look to keep these domains up-to date. You can add the custom equivalent domains personally for now, as outlined here .This PR will now be closed.
