I think its important to make a distinction between what is easiest and what people are used to. Perhaps thinking about what new users would find easiest might be helpful.
Here is an example of a well developed infobox on English Wikipedia, I think that the knowledge needed to edit this is an unreasonable barrier for casual, new or even fairly experienced if less technical editors like myself.
