Emphasizing this response. Bayesian models can always produce simple probabilities if you ask them to. E.g., given this data, what is the probability that the next flip is heads?
The fact that the model is represented as a distribution over Bernoulli parameter p doesn't contradict this: you just integrate over the posterior.
I got dragged kicking and screaming into the Bayesian world in the early 2010s when I was trying to bring back the old AI and came to the conclusion that the real problem with the old AI was lack of a systematic approach to reasoning about uncertainty and not the cost of knowledge base maintenance (e.g. that could be brought down by orders of magnitude, the value created by knowledge bases could be brought up)
One problem is aggregating information over multiple steps in the reasoning chain the other problem is the powerset problem. The point probability estimate from integrating over the posterior wasn't useful for the first, so I didn't want it. The second problem is impossible in theory but possible in practice, as the existence of intelligence proves.
