They can still pull it off without the eDRAM ... These eshop titles are not texture or shading intensive ... In this sense they would mostly be bounded by the ROPs because the setup, shading, and texture mapping/filtering stages are mostly negligible and or insignificant.
And could you expand on their reasoning on why it would be useful for the CPU to have access to the eDRAM in a significant effect ?

You still need to store your frame in a framebuffer before outputting it.
And what they said was this: "We use the eDRAM in the Wii U for the actual framebuffers, intermediate framebuffer captures, as a fast scratch memory for some CPU intense work and for other GPU memory writes. Using eDRAM properly is a simple way to get extra performance without any other optimizations."

They can do that on the main memory instead. The eDRAM isn't the only one that holds the framebuffer but that also applies to the video memory as well. Hence why graphics cards on PCs don't need eDRAM. 
The question is though does usage of eDRAM by the CPU make any noticeable difference ?

It's faster and easier to do it in eDRAM though.
And if it didn't make a difference, they wouldn't do it. Shin'en's whole programming background is one of efficiency; getting the most use out of your resources.
