It limits what peripherials can be attached. For instance, single graphic card uses 16 PCIe lanes, so having only 28 lines supported by processor makes it impossible to have two GPUs in SLI mode (ok, not impossible, because motherboard chipset can add some lanes, but performance will suffer)

NVMe SSD drives also use some lanes (typicaly 4), and you might want two of them in RAID.

Numerous tests show that performance is not meaningfully impacted by running two GPUs on 8x PCIe lanes vs 16x lanes, especially when using PCIe 3.0.

It's a huge difference for minimum frame times at 4K if you intend on getting a smooth 120fps.

with current-gen GPUs

That could also change over the next few years.

What are the chances you will still be running the CPU and motherboard you buy today in a few years?

So, if you not have plans of putting a NVM SSD plus two GPUs on SLI configuration, with 16 PCIe lanes will be enough.
