I think I found a valid use for uncacheable_rule: https://github.com/pantsbuild/pants/issues/16356

I feel like that kind of issue would benefit from some notion of how Pants could interact with an external cache

Short of trying to get clever I think the answer is "dont" 🙂 Let external tools manage themselves

bikeshed, would be nice if it was

@rule(uncachable=True)

Yeah I think that'd be the API. I think the underlying function does that
