I'm sympathetic to the idea that some people need reduced contrast to read comfortably. They are in the same boat as people who need maximum contrast because of other visual impairments, most commonly focal issues.
Why wouldn't people who need less contrast simply reduce the contrast on their monitors, though?
It seems to me as though designing for those who need low contrast excludes those who need high contrast, but not the other way around.

Because I don't want to make everything else look worse just to lower contrast in text?
And support for low contrast doesn't mean excluding others, it can just be a setting. Like Windows has been doing for a long time with its high-contrast mode. Websites and apps are increasingly adopting dark themes, next we should push for a switch between high and lower contrast. It's just as easy from a technical standpoint. Browsers are already pretty far, letting the user set specific fonts and font sizes, and Firefox' reader mode and its options are great as well.
