No you have totally lost me there ...
I've not had time to read ALL the messages in this string, but routing 
software should address the time aspect of a route, and anything below 
'secondary' should be treated as a slow route. As you say - stopping routing 
through an area has nothing to do with the highway tag ...

That is what I said
Tag a cycleway as a cycleway ;)
Rather than having to check for 'bike=no' tags.
