Agent builders say provider KV caching black boxes block swarm and long-run agents

A developer building a side project in the inference space reports that inference engineers and startups complain about the lack of manual KV cache control: provider-side caching is a black box. This is especially painful for agent swarms that want to fork agents from a shared cached prefix, and for long-running agents that need to persist a cache for later agents to hit. The poster asks whether the problem is widespread and what solutions exist.
