There can be reasons for grouping a set of elements in the DOM with a parent div besides styling. But sure, it's a "violation" but web standards do not say "you must only use elements that are essential to the semantic structure of the document." I'd say the guideline is "start with semantic elements, add others as needed for styling, programmatic access, componentization, etc."
