Intel Socket Issues

[WhiteBear]

Why did Intel create the i9 for Skylake but not for Coffeelake ?

 

I find the problem with Coffeelake is that it's limited to only upgrading to other flavors of the i7 rather if one ever wants to upgrade to the i9 which can only be done though Skylake.  I understand both are nm14 therefore I assume the difference, although I don't know the specific differences between the two is small ?

 

Also why does it appear most socket 2066 boards have some sort of problem one way or another ?
