Compiler writers aren’t that far behind? C++17 is mostly supported. C++20 is one year old!

"C++20 is one year old!"

The ISO standard was published in December of last year. So, technically, C++20 is only four months old.

For essentially any other language this would be an absurd thing to say. For those languages you wouldn't consider a feature added until it was supported by the reference compiler

If you are using GCC, Clang, or MSVC then the standards support is excellent[1].

But putting that aside

Well, there is no reference compiler for C++. I don't think any language with either an ISO or ECMA standard has a reference compiler or interpreter.

There are gaps in support here in and there. But I would still say those mainstream compilers "support" C++17 for the same reason I would say that Chrome "supports" CSS3, despite it not implementing the full specification.

Only for languages that lack multiple implementations.
