Motivation

See each commit for details.

Context

Overall goal is #13570, which #13942 will fix. Since that one has some back-compat subtitles, I want to land the prep work first.

The Nix maintainer team uses a GitHub project board to schedule and track reviews.

This is because we need it in declarations where we should not be
including the full `nlohmann/json.hpp`.

Already can clean up by moving the experimental feature "instance".

Also, make the `std::map` instance better by allowing for other
comparison functions.
Wrong number of arguments was causing a format assertion.
