After the std::optional fiasco, I'm pretty nervous about the state of
using new C++ 17 features.
We've wound up in a situation where we're OK with increasing the
compiler requirement to recent versions... as long as WebKit continues
to build with ancient libstdc++. So increasing use of more C++ 17
standard library features seems difficult, and of really limited
benefit if we're going to need to keep a fallback WTF implementation
around, which will receive limited testing from us, but which will be
used by most of our users in practice (at least for GTK).
This is a hard problem. I don't have any answers. But I don't think our
status quo is very good. https://bugs.webkit.org/show_bug.cgi?id=185198
is still unresolved and I'm out of ideas....
