I'm ok with that considering for the most part, even PCIE 3.0 is sometimes an overkill for mainstream, and for the most part, even PCIE 3.0 x8 is more than enough to not bottleneck current get GPUs.
So 5.0 even at x8 is going to be enough future proof until several generation GPUs pass on. Especially since we are only seeing now 7nm, and 5nm or lower, or a brand new tech, is still years from now.

So buy AMD if you don't like intel.
But most likely considering intel will try to keep their mainstream chips small, we won't see more pins to be available for more than 16 PCIE directly to the CPU. It might also not be needed until much later on.
Just to remind you, the DMI is not shared with the 44 lanes. Do you even know your own chip?
Also DMI is based on PCIE, so 4.0 or 5.0 will also increase DMI speeds.
