What would be the advantage vs DIMMs?

In a server, you're more limited by DIMM slots than by PCIe ports, especially on EPYC considering the number of lanes available.

With the shift towards DDR5, DDR4 could be repurposed as old servers are decommissioned.

I'm not convinced of the limited slots point - 16 (AMD) / 24 (Intel) DIMM slots in commodity single cpu socket server mobos, it gets you a few TB of RAM. 48 sockets in multi CPU socket mobos if you need more.

I can see "recycling refurbished previous-gen DIMMs" working for certain cases but it sounds a bit niche unless someone productises it really well.
