One more thought that just crossed my mind on disabling the POVD by default (which essentially would mean to remove this feature for anyone who is not very well versed in Anduril): Regarding the battery voltage, there has not only been the introduction of the POVD, but also the introduction of a two-decimal battery check via 3C from Off. The two-decimal reading is more precise than the previous one-decimal reading, but it also takes longer, and apparently not everyone likes it.
Personally, I like the quick POVD, and I also like to have the slow two-decimal reading via 3C from Off at hand. These two, the quick and the slow, go very well together. Taking away (essentially) the quick POVD would result in an imbalance, because then - apart from setting the aux LED color to voltage - there would only be the slow two-decimal reading left. Does this make sense?
