This model seems super expensive! I interpret it as traces on steroids which will make query complex and slow!

A lot of businesses haven't even nailed simple histograms with prometheus. I wouldn't like observability to become a full set of problems on its own!

Also timeseries is powerfull in observability because a lot of issues can be represented as cheap counters, gauges and distributions. I want to see a paradigm complimentary to this simple principle instead of producing nested documents with nested objects.
