I have definitely seen this "you need to go deep in the settings to enable 3rd party installs at all" flow before, but I don't remember which device it was. (Just saying that the commenter above is not just inventing something, I was surprised when I saw it as well)

The point being that there is not a whole lot of friction in this flow -- one or two taps -- likely making it easy for scammers to coach victims to perform.
I agree that activating the developer settings menu is substantially more friction, and may arouse more suspicion in a victim, but [on many/most devices] is not currently required. I guess the original article is alluding to putting this kind of friction in place.
