transit – Any updates on UK layovers restricted entry to US?


I read here that someone having a layover in the given areas would also be restricted entry to the US. I’m an F1 student and am planning to fly from US to India for a month in December. The CDC site was last updated on September 14, which is a month ago. I could not find an updated list of rules for nonimmigrants. As of now, I’m looking to book a flight that has a layover at LHR in London, which would put me in the list of restricted people on the way back. Is there a way I can confirm somewhere if that is the case and I should look for alternatives?
