Hey Liam,
Thanks for the question. I’ve checked with the team and this isn’t widely used at the moment (internally), which from my perspective I’d probably suggest to not adopt it at this point. The best advice I can give in this space is to more or less go with Zen /CloudDDC setup at this point in time.
Regarding the Symbol Server, I’d hesitate to say that this is beyond experimental. Let me speak with some of our internal team to see what the status is.
Regards,
Julian
