I think there are a surprising number of people who would use two x16 slots (not the latest generation bandwidth requirements, just the electrical connection to support older products at full speed), one for a GPU, one for something like a networking or storage card. But it makes workstation and server class offerings weaker in comparison. |

NICs that can utilize x8 from PCIe 5.0 or even 4.0 probably don't usually go into consumer or even prosumer hardware. PCIe 3.0 x4 is enough for a single 10G NIC. One PCIe 4.0 x8 can handle 4 of those, double that on PCIe 5.0.
There is currently no GPU on a market with PCIe interface that can utilize PCIe 5.0 x8 fully.
Storage is probably the only area where what you get from PCIe is not enough. However, by the time such bandwidth makes sense - the price of CPU and motherboard is a drop in a bucket, and you are probably limited by more than just the number of PCIe lines.
