I agree. Somewhat related to this, the WG has already resolved to add an  
API for extracting glyph outlines as path data:

https://www.w3.org/Graphics/SVG/WG/wiki/SVG2_Requirements_Input#Consider_adding_a_DOM_method_to_convert_a_.3Ctext.3E_element_to_outline_path_data

Adding a getBBox method to SVGPathSegList (or it's future replacement)  
might be one way to do this, or alternatively one could create a path  
element from that path data and query the bbox from there.
