That's unnecessary moving part IMHO. Is it still the case or they changed their architecture recently?
There were ample reasons in the past whereby going down this path made architectural sense. The primary one being multi-language support. Since then, TS and JS have found their way to the top of "the programming langs of choice" charts and so we're digging into removing the Rust based components and making them optional.
We'll share more on this in the coming weeks.
Partly this is what makes this a fun and interesting challenge that goes beyond just the tech and the team is eager to get their hands dirty to solve this. For now, lots of ideas on the board. Once we have a plan, we will start to share in order to get community feedback.
