At present this is an experiment. There is no commitment to merge branch cc-experiment in a future Scala 3 release. But it's not excluded either. The aim of the experiment is to find out how useful capture tracking would be, and conversely how much of a burden it would be. If the balance is clearly towards usefulness, we might work on a full release candidate in the future.
