What is the prevailing opinion in scientific community about Hans C. Ohanian's description of spin? In the paper What is spin?,  Am. J. Phys. 54 (1986) 500, by Hans C. Ohanian, spin is described as a circulating flow of energy in the wave-field of a particle. Is this the generally agreed upon explanation of intrinsic angular momentum or just a fringe theory?
(A similar thread exists on Reddit, but I couldn't find a satisfactory discussion there.)
 A: Ohanian's paper shows that spin can be understood as a circulating flow of energy, and is a wave property, valid in both classical and quantum mechanical formulations, rather than inherently and mysteriously "quantum mechanical" in nature.  A fine point not needed for calculations that can be ignored by the pragmatic experimental physicist.  But to me (and apparently the author) it's comforting to have physical intuition so lacking in much of conventional qm.
A: I read the abstract.
The basic reason it is not referred to or used is that main stream physics has elementary particles as point particles in the standard model and any wave nature attributed to the particle is on the probability distribution of its location in space and time. 

it can be shown that the spin may be regarded as an angular momentum generated by a circulating flow of energy in the wave field of the electron. 

A point particle can have no circulating flow of energy. So it may be a correct mathematically description but not within the language/model of mainstream particle physics at present.
