'main' is already one of the subclass roles of landmark[1], many of which have have direct 1:1 default role mappings to new HTML5 elements (e.g. nav[role=navigation], footer[role=contentinfo]) and the proposal is, in part, to have an element on which to hang the default semantics of the 'main' landmark role. The accessibility role default is one important argument, but there were several others raised in favor of the element, including the semantic clarity or heuristic ease for readability/reader that you mentioned, as well as CSS hooks, script hooks, and other organizational benefit for content authors.
