Why did a bunch of options in the new debug menu in SteamVR get removed recently?

As a post on the Vive subreddit mentioned about 1 or 2 weeks ago, (This one: https://www.reddit.com/r/Vive/comments/bvku6c/psa_you_can_turn_off_the_mura_correction_now/) we were finally given the option to toggle Mura Correction and Black Clamp on or off. I'm not sure how many people have this issue. but there's a small hardware defect in some Vives like mine where one lense has been configured differently than the other in how strong the mura correction is. This results in one eye feeling blind when in very dark scenes, and once your eyes adjust to notice it, it becomes very distracting and annoying. For some people the Mura Correction toggle fixed this. For others - like me - the Black Clamp toggle fixed this. But for whatever reason it has since been removed from the menu, so I can't turn this off anymore. Does anyone know what's going on?
