I think the routing people need to decide on that one - I'd just been 
imagining them preferring not to have to spend too much time checking the 
tags on every single node?

No-Entry is also problematical in that it's often typed - there are lots of 
roads which are 2 way on bikes but 1 way by car - and cycle routing is 
something I'd love to see - it's not met anywhere currently.

Anyway I certainly don't know what's best!
