Imo, those are the currently discussed solutions because of the lack of available testing. Ie, with the current constraints. It's akin to two people discussing how to use the budget of $1 million and a third saying "I have a third solution: Make the budget $100 million and do everything". Sure, it's not wrong, and it's different to the first two, but... who cares? Everyone kind of already knows if you have the $100 million you have a much better option.
