>You've got to support the API forever Not really. Many APIs have features that are put in and removed all the time. The key to managing this is having a good API that tags features as things like 'experimental', 'deprecated', 'locked', etc to indicate if features are permanent or could be changing. Stability: 0 - Deprecated This feature is known to be problematic, and changes are planned. Do not rely on it. Use of the feature may cause warnings. Backwards compatibility should not be expected. Stability: 1 - Experimental This feature was introduced recently, and may change or be removed in future versions. Please try it out and provide feedback. If it addresses a use-case that is important to you, tell the node core team. Stability: 2 - Unstable The API is in the process of settling, but has not yet had sufficient real-world testing to be considered stable. Backwards-compatibility will be maintained if reasonable. Stability: 3 - Stable The API has proven satisfactory, but cleanup in the underlying code may cause minor changes. Backwards-compatibility is guaranteed. Stability: 4 - API Frozen This API has been tested extensively in production and is unlikely to ever have to change. Stability: 5 - Locked Unless serious bugs are found, this code will not ever change. Please do not suggest changes in this area; they will be refused.
