Regarding caching and memoisation. Isn't the main benefit memory usage saving. I wonder if it's possible to do parsing for speed and then background deduplication for memory savings. (I don't know what the status is of multithreading in js or wasm)

Huh? Caching is explicitly about extracting time savings at the cost of increased memory usage. Did I read your comment wrong?
