So I guess DDR5 still has a little bit of time here. Anyone know if this also affects LPDDR5x?

The DRAM interface is pretty well decoupled from the memory array itself. So whether you're looking at DDR5 or LPDDR5(x) or GDDR6(x) or HBM3(e) isn't the right question. What matters are the implementation details up to the manufacturer's discretion, such as on-die ECC.
