Everything is either in development or stable. There aren't statuses like alpha, beta, release candidate, etc. except for individual library releases. Metric clients will be marked as "development" until it goes "stable" [0]. Consequently it can be hard to determine the actual maturity level of any given implementation.
Tracing is very mature, with metric and logging implementations stable for a number of popular languages [1].
the "experimental" status was renamed "development"
