You could, yeah.

You could put in a lot of work, just for read-only feature parity.

Or you could work some more, and have a competing product.

You seem adamant, that the former is a better path, but I don't quite see why would you do all that work for naught.

(Roam already broke my backup script 2 times, and there are better uses of my time than interfacing with a proprietary product, if there are better alternatives.)

I'd say a parser is an order of magnitude less work, but if someone wants to make a full product I'm not going to try to stop them.
