Inspired by my more specific question on LWG 1203.
I've noted that this page lists C++ Standard Library Defect Reports (LWGxxxx). As I understand, if they are marked with "C++20", "C++17", etc, they are retroactively applied to already published C++ standards. There is a similar page for Core Language Defect Reports (CWGxxxx).
However, some proposals, like P2216R3 also got voted to become a Defect Report against C++20, as indicated in its "LEWG Polls (R1)" section. Unfortunately, it is not listed on either LWG/CWG pages and I was unable to find poll results for its more recent R3.
So I'm wondering: is there a full list of defect reports against older standards (C++20, C++17, etc)?
