I have two concerns with that proposal:
1. It was working fine for months. We should not have to update every segment on the map to adapt to changes to the back end that we don't even know were intentional. Ehud also mentioned we should not try to work around things that appear broken because they are constantly making changes that may or may not stay.
2. I am pretty sure that I found when you have unnamed segments, the turn by turn instructions on the client show "..." for those unnamed segments. I have personally experienced the problem and when trying to determine which route to take the turn by turn instructions left out major named turns, so I was not sure what route it was actually taking. After filling in all the segment names it worked fine.
