Actually, I'm not certain if you save any time by constructing a DOM tree and dumping it in all at once (but I could be wrong). It would save on mutation events, though. I do see your use case, and have updated the wiki [1] and my prototype implementation [2]. However, I will note that since SVG is so attribute-heavy, many if not most elements will not require child content, especially if you aren't using SMIL, so I think the insertion constructors are still extremely useful, so I've kept them in. I'm also interested to hear feedback about our more general thoughts and ideas [3], especially from implementers.
