<tspan> and getBBox()

In SVG 1.1  <text /> implements SVGTextPositioningElement and SVGTransformable (which in turn implments SVGLocatable and thus gives <text/> getBBox() )
<tspan /> doesn't implement SVGTransformable

I see in the SVG 2 draft spec indicates "SVG 2 will allow transforms on 'tspan'" (http://www.w3.org/TR/SVG2/text.html#TSpanElement ).
Does this mean that <tspan /> will implement SVGTransformable and finally get the much needed getBBox() function/method?

SVGTSpanElement  interface should inherit from SVGTransformable in that case, correct?
