The challenge is minimizing the difficulty of the task for the voter. Any additional thing you ask a voter is something they can get wrong. Once you look at things through a lens like this, it really changes your thinking. That's why plain vanilla bubble-form paper ballots are so attractive: the task you're asking the voter to do is straightforward and simple (with the clear exception of straight ticket issues).

In essence, complexity is the dragon that we need to slay. Anything that can reduce complexity is desirable, even if that means changing things around. Example 1: North Carolina's unique straight ticket rules. Example 2: Australia's incomprehensible preference scheme. There are many others.

(In Australia, voters are effectively asked to specify a permutation of maybe 100 different candidates for Parliament. Since this task is virtually impossible to do without error, the parties helpfully offer "macros" where you can say "I'll have what they recommend" with a single checkbox. The major parties will, of course, put their candidates first and will put their natural competition, who voters might rationally desire as a second choice, all the way at the bottom. I'm told that something like 95% of Australians use the "macro" option rather than specifying their own permutation of the candidates.)
