Hi hoak !
Your question on Superfetch is very interesting.
Secr9tos took R2 kernel to pieces to explore it and it results that the function is there but "hidden/removed" by M$.
It looks like that the code itself seems to be "removed/hidden" but in fact it gets invoked like it would be on Windows 7.
So all what we did is to get it working nothing more.
We did not mod the kernel as that could cause security issues and instability in the system, and we do not want that.
In what refers to components removal like in vLite or RT Server Tool from Ben, I did mention that I tested R2 "Light" releases and made some with those tools and I was not very pleased on the results.
I noticed when making some W7/R2 "Light" releases that removing components can be a problem at one moment or the other.
But we can always think about it in the future.
