And all are always hidden the way SVG is defined, so not relevant to CSS.  
And even if, the context would probably be enough in most cases.

Designing for the unknown future sounds like a waste of time and effort to  
me. I forward compatibility is important, but adding a ton of complexity  
for a need that may emerge in the future seems unsound.

There's not a lot of overlap in element names and there's always an  
ancestor you can bounce of on so I do not think this is true.
