That’s not an argument for anything. It amounts to just saying “worse is better” because you have a preference for how it looks with auto, even though being explicit with the type information is not about you.

There’s absolutely no sense in which less explicit information is somehow better for code readers. The only reason you might choose to pay the cost of having less explicit type info is if it gives you some other benefit, like shortening syntax.

But since typedef/typename offer that too, without the loss of being explicit, it just means auto would be a suboptimal choice even in the shorter/simpler case too.
