The topic at hand is material that's in the PHB but not in the SRD, and the workarounds that that requires. Reframing it to a matter of mere convenience is a different debate.
I don't believe that to be the case; you've posited that the author feels that such material "has" to be there, that it's a necessary work-around, and I don't grant that particular premise.
That's why I went with 80 pages of material rather than, say, 10. The latter is small enough that the PDF may or may not cost more, but with 80 pages, amounting to a quarter of the book, there's little doubt.
Again, that's a presumption, and not one that I think is necessarily the case. I've seen larger works of original material than that given away for free before, so I don't believe that "there's little doubt" is so.
80 pages in a 320-page document isn't a minor loss, and if it's workarounds for PHB but not SRD material it's not bonus material, it's material that the author feels he needs but which actually adds no actual value.
Once again, you're presuming this to be self-evident when it's actually anything but. It could very well be considered bonus material in that the author recognizes that you're going to have the PHB on-hand if you're using this material, but has provided an OGL equivalent purely to reduce page-flipping. The author does not feel that he "needs" it there, nor does he find it to add no actual value.
I'm paying for things that I don't want and that actually reduce the value of the book. If the material was in the SRD in the first place, those workarounds wouldn't be necessary, and while mentally translating from "Woodland Gnome" to "Forest Gnome" every time is a minor annoyance, it's more of an annoyance than not having to do it. The fewer workarounds are required, the better.
That only reduces the value of the book
to you, and beyond your personal opinion there's no particular substance to that objection, since you can't establish that that material has driven up the cost of the book, nor that other people don't want said material. Hence, you don't have any particular point upon which you can say that the value of the book has been reduced in any capacity beyond whether or not you yourself would want to buy it. Others will find that their mileage varies.
Insofar as being more convenient if that material were in the SRD in the first place, that's the problem that these hypothetical new additions fix.
