It seems to be a rather limited view, mostly intended to facilitate
education. It doesn't link up at all with the statistical thermodynamics
perspective.

Yes, there is something pretty entropy-like in how action gets
extremalised. People have been working on the links between the action
principle and the principle of maximum probability (after all, the
Feynmann path integral is a kind of probability maximization).

There might even be a link to evolution, see

(not sure whether this actually holds; evolution occurs in open systems
after all)
