Yes, I know it isn't. I had to buy it separately, after trying it out for a couple weeks. The quick launch docks are buggy, but the tabbed docks are just what I wanted. Deskscapes8 work well surprisingly. Would love to find more effects for it or at least a manual on how to make them.
There were a few Win 8 apps included which I figured wouldn't run under 10. I didn't pay that much attention to the list because there were only I few items I really wanted.
Decor8, IconDeveloper, ModernMix, SoundPackager (darn!), Tweak7 were the others the Desktop Manager listed.
I haven't tried Fences 3 (tried it out before though, not something I'm interested in atm). Haven't had time to look at Launch, Multiplicity 3KM, SpaceMonger 3, Start10, Tiles & FX 6 yet. Tiles looks interesting.
You're missing the point though. I ran an online business for years. The golden rule is THE CUSTOMER COMES FIRST. You shouldn't even have to think about whether this is critical information for your buyers.
