I suppose in this instance it's explained that it's mandatory and the reasons for that, so if "want" or "need" is used correctly is just semantics, although I do see where your coming from.
More important for decussion is if that's a possible option, which as pointed out I don't believe so to get approval, this was talked about for Neo.

An option that hasn't been pitched is to make do with a cheap "dumb" phone or if must android device in the short term? At least until devices tick more of your boxes.
I am hopeful Pine with keyboard will be the right option for me in future.
