Someone asked, is "ML pipelines" stable? I said, no, most of the key classes are still marked @Experimental, which matches my expression that things may still be subject to change.
But then, I see that MLlib classes, which are de facto not seeing much further work and no API change, are also mostly marked @Experimental. If, generally, no more significant work is going into MLlib classes, is it time to remove most or all of those labels, to keep it meaningful? Sean
