2. This board in particular uses a chipset from 2011; of course it doesn't have M.2. I'm sure most users of this board used PCIe SSDs anyway. It was just a quick google search result.
3. In a platform this high-end, it's frowned upon to use an integrated SAS. They include SATA specifically because it isn't enterprise-class.
4. Is BMC common for workstation motherboards? That seems a bit picky. Looking at the specs of the model you picked out, it has built-in VGA, a relatively low amount of USB ports, BMC support, and Epyc support. To me, that means it's targeted toward servers, not workstations. Obviously nothing is preventing you from using this as a workstation.
I don't deny that's an impressive board for it's size, but my point still stands that board real-estate isn't conclusively the issue. And yeah I get it - there isn't really any enterprise hardware where you can populate every single slot with an x16 lane card, but ultimately what I'm getting at is the lanes are available so why not supply them anyway? If having x16 was definitively pointless, Supermicro would've only supplied x8 slots and/or AMD would've provided fewer lanes. But, to give AMD some slack, Epyc is effectively just a doubled-up Threadripper, so I'm sure the extra lanes was more of an unintentional bonus.
