I do think you are being harsh here, or at least too particular to your own experience. My experience differs. As a practicing scientist who also did a thesis on the concept of Causality, with projects on Time, I did in fact have to interact with and learn significant physics to make a dent in my projects. My professors were themselves extraordinarily capable with respect to (at least theoretical) science. My graduate-level philosophy of science classes were significantly harder than my theoretical physics classes, in some regards. The insight with respect to what is 'experimentable', and to be able to trace logical consequences of scientific assumptions through to experimental effects, and then to challenge those most basic of scientific assumptions by designing and using an experiment made powerful by its relation to an underlying philosophically-derived framework was extraordinarily empowering. And that's on the philosophy side. I'd also argue that the framework instilled by my philosophy of science education has made my work as a scientist significantly more generalizable, and thus more influential to my fields.
