Pretty sure this rule of thumb was created during the days of 4TB and 6TB spinning disks. Newer spinning disks and SSD / NVMe are faster so they can have more PGs. Obviously a 16TB spinning disk isn't 4 times faster than a 4TB one, so it's not a linear increase, but I think going closer to 200 should be fine for the bigger disks.
