GCC 16 considering changing default to C++20

Where do you draw the line for properly supported? I've been using g++ in c++23 mode for quite some time now - even if every feature is not entirely implemented, the ones that work, work well and are a huge improvement

I draw the line where I can't expect the default gcc on most Linux and Mac systems to compile my code. And I don't want to force them to install a particular compiler. -std=c++20 seems to work pretty reliably these days.

We're starting to need caniuse.com for C++.
