This setting takes the cake for longest description at ~7000 characters. It is too long to fit in the settings UI and seems to be mostly listing defaults? Is there a reason those defaults aren't just actual defaults for the setting? For me to read the whole setting description I must click the "open default settings" link in the description and then scroll to find this setting in the list.
cc @rzhao271 for how settings UI handles descriptions which are too long.
