16GB optanes with an ordinary SSD interface are pretty widespread in China and DIYers do use them for swap/pagefile. The problem is that they take up a whole M.2 or NVMe slot with the corresponding number of PCIe lanes… These drives generally come from budget laptops where the optane is originally used as the system disk. Not a good idea anyways and computer shops usually swap them out. You pay about 28 CNY for 16 GB, which is 2x the average SSD price-per-gig.

DRAM interfaced Optane wouldn't consume NVMe lanes. It should be soldered same way as usual DRAM is soldered in most non-professional (but home or bussiness) notebooks this days. For example: MacBook M1/M2 has fixed limiter RAM. But with Optane as swap it could be four-eight times larger without user notice on difference.
