thank you for pointing to this documentation issue. The functionality to delete applications was
removed in Kaa Archipelago because it is generally unsafe to remove data that could be used for generating endpoint SDKs (and releasing applications based on such SDKs). Therefore, applications and all versioned schemas are currently immutable: you can create a new one next to the old one, but you can't remove any.
This will change in Banana Beach with the implementation of
KAA-445, and several related stories. We will start keeping track of
SDK profiles and know whether they are actually in use by any of the endpoints.
