Yep; sadly still true. I started some work last year to simultaneously add support for arbitrary JSON data and add a database-like storage layer to allow us to safely stream changes to disk. (Automerge and yjs usually require the entire data set to be re-saved in its entirety when updates happen). Its taken longer than I thought, because I've gone through a bunch of different designs for both pieces. We'll get there; everything just takes longer than you want when you do it for the first time.

I'll look at autosurgeon. Having similar APIs is good for everyone.
