Whether or not this is useful (I am also not sure), the JSON doesn't need to survive into runtime at all. If you include the JSON, do a bunch of `if constexpr`, and never touch the JSON outside of a constexpr context, it doesn't have to any footprint on your binary. (I'm not sure if #embed will force stuff to stay in your binary even if you never reference it at runtime)

That's what I meant by "even if it's transformed". Parsing JSON at compile-time to store in some global variable/constant is highly sus imho.
