Eh, it's fine, elements should be defined for what they mean, not what they look like. The explanation and distinctions made between <b> and other elements (<i>, <em>, <strong>) make sense.

The suggested (not obligatory) user agent styling for <b> is `font-weight: bolder` an agent or authors could use lots of different things to bring attention to what the element contains and treat it differently from <strong>.
