Avira > eisav had lost his yerushah when yaakov got the brochos;
Right, but Yaakov is somehow still worrying… Maybe he did not learn those Rashis. Maybe this is a part of Yaakov’s middah of Emes that he is always questioning whether he is good enough and sees zechuyos of others even if there is a tirutz. I can easily see a modern “learned” version of Yaakov meeting Esav’s malach and then proving to him that Esav has no olam habo, etc, convincing the malach to just give up.
