On the other hand, you're also stuck with design mistakes for ages.
The AM5 platform is quite lacking when it comes to PCIe lanes - especially once you take USB4 into account. I'm hoping my current setup from 2019 survives until AM6 - but it seems AMD wants to keep AM5 for another generation or two...
There's minimal demand for Thunderbolt/USB4 ports on Windows desktops. It won't ever make sense to inflate CPU pin count specifically for that use case, especially when the requisite PCIe lanes don't have to come directly from the CPU.
You'd be better off complaining about how Threadripper CPUs and motherboards are priced out of the enthusiast consumer market, than asking for the mainstream CPU platform to be made more expensive with the addition of IO that the vast majority of mainstream customers don't want to pay for.
One person's "design mistake" is another person's "market segmentation".
x16 GPU + x4 NVMe + x4 USB = 24 direct CPU lanes covers 99% of the market, with add-ons behind the shared chipset bandwidth. The other 1% of the market are pushed to buy Threadripper/Epyc.
