[webkit-dev] Using C++20 in WebKit

In April 2019 in https://bugs.webkit.org/show_bug.cgi?id=197131 <https://bugs.webkit.org/show_bug.cgi?id=197131> I increased WebKit’s minimum C++ language requirement from C++14 to C++17. In 2022 I’m planning to increase WebKit’s minimum C++ requirement from C++17 to C++20. Would April 2022 be a good time to do that?
