 The spirit of this policy is to make sure that effectively, no library published for Scala 3 contain experimental features. This way, what is experimental can be easily changed and is not subject to the guarantees of the wider language. And, most importantly, the changes to such features would not affect the community *in practice* – the guarantee not achievable if we just announced the policy without implementing a mechanism to enforce it.

Without the curious and adventurous part of the community playing with the new features, there is no way of knowing what they are good for, and no way to decide whether they should be dropped or promoted to a stable feature.
