Review comment:
       If we removed the routes now, how badly would CIAB fail? Obviously the 
caches wouldn't be able to handle requests, but is there anything else? Does it 
prevent other service from starting?
   
   If is just breaks the caching in CIAB but all the other services start up 
fine, I don't really see a problem breaking that functionality temporarily (as 
well as the TP functionality). Most of the automated testing I know about that 
depends on CIAB doesn't require the caches to successfully handle requests 
(unless you count the readiness container).
