Should Wiktionary votes cast be required to have a rationale?

In various places where iconized votes are cast, including formal votes, Beer parlour polls and discussions and requests for deletion, users often post rationale-free and comment-free supports or opposes. Should this be disallowed?

Pro

 * Requiring rationale bolsters the idea that arguments matter and that mere unanalyzed opinions should not prevail.
 * It helps prevent or reduce government by the unthoughtful and inarticulate.

Con

 * That is excessive, requiring editors to articulate the obvious.
 * Not really; only one editor has to articulate the matter and the other editors can say "per editor Joe".
 * That results in an hard-to-read echo chamber, where editors try to outdo each other in articulation.
 * Not really; only one editor has to articulate the matter and the other editors can say "per editor Joe".
 * True in principle, but the policy of requiring rationales is still likely to contribute to people trying to articulate on their own.
 * That is not obvious. But if it is true, the policy can also say something to the effect of: if you have no genuinely new arguments to add, it is often preferable that you state "per editor so-and-so" over rearticulation of what has already been said.
 * People articulating on their own does not need to be a bad thing: one trying to put someone else's argument into their own words often activates the thinking and imaginative parts of the mind and can often discover elements of arguments that are new.
 * This scales poorly: if we have 500 voters and each tries to do original articulation, the poor closing editors has to aggregate and collate 500 arguments. This task is greatly relieved if one says merely "per editor so-and-so".
 * True enough. Then, editors should be encouraged to use the "per editor X" form whenever they see the vote or discussion has already a lot of participants delivering solid arguments.
 * Wiktionary processes usually do not have so many voters; they are glad to get 50 voters, and it is all too usual to get on the order of 10. This issue exists in principle but does not occur in practice.
