I understand that this is mostly a matter of taste in API design, but IMHO
that's an anti-pattern. It encourages poor style; it discourages
functional programming patterns, instead favouring state mutation
patterns; it makes APIs harder to extend; it makes APIs that do have
useful return values inconsistent with other APIs; it is, in fact, a
layering violation: it attempts to shoehorn what should be a language
design feature into the API layer.
But I'll leave it up to the DOM guys to decide what to do for that
