As we have seen that blogger has launched dynamic views for templates and it looks pretty awesome for user point of view, but actually it hurts your SERP performance and google search, It won't be able to list your newly added posts and pages. You will see your web traffic is declining in few days. Also, you can't change any layout elements, can't help with Adsense javascript. It won't show any script. It is not working for bloggers who wish to earn from their blogs. You can't even edit Header or upload pic.

Dynamic View templates are just formal plain RSS to show up your blog nice and clean without any messiness. It will hurt your blog's performance and you can't make money through any advertisement.
I think it just need some touch up to address those issues before it gets wide acceptance from public.
