I do think that some slight changes are in order here.
Here is a list of things that probably should be altered or removed.

1. I do believe that 'backface culling' means that when rendering, either the backfaces are exclusively rendered or ignored from the render for performance boosts. (By only rendering what is visible to the camera, performance is saved) This means that it effects the final render, I believe that the 'in final render' should be kept because backface culling is used within the final render, if the user selects that as their option.
2. I do disagree with the change of backside to backface. I think this is misleading, let me explain. A backface is by definition most simply, 'a face on the back'. This is why backface culling makes sense to use as terminology, because it is culling the backfaces. But backside means that anything on the back, which can be multiple faces. Changing backside to backface is incorrect because backface means one face on the back, but there can be multiple faces on the back. This is why backside should be used when referring to all faces on the back.
3. I do not know why you would remove '_bpy.types.Material.alpha_threshold:'(Line 73) as it seems that this line is still relevant to the previously mentioned alpha threshold value within the document.
4. I also slightly disagree with the last change, where clip and hash are changed to alpha clip and alpha hash. I believe that this is incorrect. Clip and hash are modified by alpha and clip value, but are not directly 'alpha', which is why I do not think this should be changed.
