I’m reading the wikipedia article on this but can’t find any mention of safety regulations relating to the temperatures at which hot beverages must be served. It says that “… McDonald’s required franchisees to hold coffee at 180–190 °F (82–88 °C) … coffee they had tested all over the city was served at a temperature at least 20 °F (11 °C) lower than McDonald’s coffee.”

Only mention of 130F was made by McDonald’s quality control manager Christopher Appleton who “… argued that all foods hotter than 130 °F (54 °C) constituted a burn hazard, and that restaurants had more pressing dangers to worry about.”

I struggle to understand what the optimal resolution to this would be. You need boiling water to brew coffee. That’s a fact which any coffee snob can confirm. While it’s not a technical impossibility to serve coffee at lower temperatures, a regulation like this would make it near impossible for coffee shops to serve fresh coffee and this applies to tea aswell.
