Will you change WebKit's GCC version policy?
If so, what will be the minimum supported versions of GCC, Clang and MSVC?

According to the Clang C++ conformance page, it doesn't fully support
Coroutines yet.
Do you know  which Clang version has started to support it partially?
Which part of Coroutines is supported by the version of Clang?
