Is there an official production-ready solution for getting the 'Live Query' unofficial feature working? (I'm not talking about 'subscription')

I've found some [1] [2] [3], but they're either archived or not ready for production.

I want to register from my clients (frontend app) for specific (can be complex) queries and get updates on changes.
