where required C++ version is not supported?

Add requirements to you tests Jamfile, something like:

import config : requires ;

project /boost/gil/test
    : requirements
    [ requires
        cxx11_constexpr
        cxx11_decltype
        cxx11_template_aliases
        cxx11_variadic_templates
    ]

(those checks come from Config library which most likely you are pulling
already in your CI builds).

I noticed that some libraris specify "std" in libraries.json, for example:
> - Any: "std": [ "c++17" ]
> - Ratio: "std": [ "proposal" ]
> What is the purpose of these?
> Is this respected by regression builds?

I doubt those do anything. IIUC `libraries.json` is used only for
https://www.boost.org/doc/libs/ list generation.
