The best place to check out the properties of alkyd materials is from the source. The prime manufacturers of alkyd resins provide tech sheets which note increased de-lamination of alkyd paints with the admixture of linseed oil, and all prescribe the necessity of "sanding" between coats to insure proper adhesion. It is not the nature of the material to allow for solvent transfers and chemical bonds which occur when natural resins are employed in oil painting.
You will find that painters seem to form an emotional attachment to the materials they prefer, which appeals to logic or scientific evidence often cannot deter. I'll admit I'm no exception. Read the thread "Lovely Alizarin" which both proves the point, and offers a reasonable answer. If one is concerned with permanence, the burden of proof lies with any materials or methods that enter the picture after 1630. Oil painting was perfected even before that date, to which the great number of 500 year old paintings attest. Why look further?
