I've seen your initial code (actually the patch only) and it think it is going in the right direction. A few ago I responded to a similar question proposing a solution like you now implemented it. As the ajax header response "replaces" the DOM it might not be a problem for ajax components but rendering a whole page the more difficult thing was with header contribution exclusion e.g. multiple MyLabelWithJavascript components on the page to be rendered just once, markup inheritance etc.
