Description

It may be the case that the feature is abandoned, but the macros seem to be widely ignored and instead the symbols are just typed from the namespace nlohmann or, ::nlohmann

Reproduction steps

Try to build with a renamed namespace

Actual: multiple compilation errors where the macro is not respected
