In may experience, a lot of the original NaPTAN imports have decayed:

- people have double mapped stops and the the NaPTAN one has been deleted;

- stop have moved and got double mapped and deleted as a result;

- stops have been temporarily out of service, e.g whilst redeveloping a 
bus station, and been deleted and then lost the NaPTAN associations when 

Also, all bus stops need continual maintenance because names get changed 
  as landmarks come and go.

Given that few people like maintenance work, if you can't map all the 
stops from first principles, it is very unlikely that imported ones will 
get maintained.  Retaining the NaPTAN tagging is important in allowing 
any later remerge of the updated NaPTAN data.

Another problem with NaPTAN stops, which applies to non-OSM users as 
well is that they have virtual stops in Hail and Ride areas.  Routers 
seem to only like people boarding at those place, so, in my case, can 
take me about 7 minutes out of my way against the direction of travel, 
so tell me I have missed a bus that could be easily caught.
