Sorry yes, i was thinking of the context object with source parameter.
The issue it solves is a big one though, since without it the JSON.parse functionality cannot parse numbers that are larger than 64bit float numbers (f.ex. bigints).

What you are probably thinking of is the context parameter of the reviver callback. That is relatively recent and mostly a qol improvement
