Yes of course. But users do want to be warned about their own code. And if
Boost.Config disables the warning, they won't be, even if they don't use
variant at all.

Antony Polukhin, I believe.

https://github.com/boostorg/boost/blob/80e75653fcd6b9ad145f9a103d5c5a592a221c90/libs/maintainers.txt#L173

Note by the way that MSVC honors the #pragma warning even if it's applied
locally around the __forceinline function: https://godbolt.org/z/sW99TYa66

So the variant header can do this, without affecting other uses.

Is there an issue in boostorg/variant about this problem?
