We must be turned toward the future, I agree.

What part of HTML 5 will be problematic in your eyes? I am assuming Structural tags
such as <header>, <nav>, <article>, <section>, <aside>, <footer> which can't be styled with CSS in 
IE7. Or even worse, will not be rendered at all!?

Could we have a fall back solution to conciliate both worlds?

We need also to think of mobile devices which will become more and more common. But I would be more 
confident as they mostly rely on modern rendering engines.
