There are certainly use-cases for something like that, but let's
be clear about it: that's a niche case of interest to developers
and pretty much nobody else. For ordinary users, what matters about
the node tree storage format is compactness and speed of loading.
Our existing format is certainly not great on those metrics, but
I do not see how "let's use JSON!" is a route to improvement.
