Well the decision was made to not restore objects that were deleted by
decliners. There was no special handling of TIGER data. There are some
good arguments for this approach but it also creates some problems.
Probably particularly in the US where the TIGER data is sometimes so
bad that mappers choose to just delete it and start from scratch. I'm
honestly not sure if it would have been better overall if deleted
objects had been restored or not. It would probably have led to a lot
of duplicated roads and overlapping things which are pretty hard to
deal with.

The good news is that TIGER data is still available to help in
remapping. The TIGER 2011 tiles were recently discussed on this
mailing list:
