I don't see that the Prime Minister has to spend time constantly making cooing noises to a pack of grand-standing, pork-barrelling independents as a feature.
It is absolutely possible to govern from a minority party. But it's rare, and such governments tend not to be considered very good. In the pathological case, negotiations can leave you without a government for years. In jurisdictions where the executive is separate, that's not really a problem. In fused jurisdictions, it is.
