I would sure rather have a extremely asymmetric ration than a 'proper' ratio 
with the same upstream bandwidth.

I really doubt that choosing to badly support extreme ratios will stop or even 
slow down the deployment, and the technology continues to develop in ways that 
make such ratios more common (it's much easier to spend money on signal 
processing for a central box than for all the endpoint products)
