Indeed you did, but thank you for succintly reiterating them anyways.
My question was more directed towards the community as a whole to find
out what they expect of a JSON library.

Been there, done that years ago:

So most (all?) values are stored on the heap?

The reason I am asking about these questions is that your current design
may not be suitable for making these extensions. You really should
consider building a Boost.Serialization input archive to investigate if
your design holds.
If your design becomes a Boost library, then there will be very little
incentive to include yet another JSON library to handle the remaining
use cases. That is why I am asking these questions up-front.
Notice that with the right design we can support all of these use cases
without making the library more complex.
