Dear Andrew, Thank you for bringing this important topic on the discussion board. Much appreciated the effort you & your team have been putting on improving openstreetmap data for quite some time.
I do agree with your observation on this but we need more discussions before reaching a more concrete conclusion. The classification schemes on OSM Bangladesh wiki was drafted in very initial stage considering the standard highway attribution from the governing body of highways in Bangladesh RHD. Though for last couple of years we have been suggesting on trainings & mapathons to consider physical state & use case while putting the road tags. We are drafting another road tag schema for Bangladesh & soon will put it on discussion board. For the time being we are open to any suggestions coming on the way. For the specific change-sets you mentioned me personally would suggest to leave mirpur road as primary Road rather than Trunk. considering the use case specifically in terms of vehicle types on the road. And offcourse that will impact the routing especially if you take Speed limit & ETA under consideration too. Would surely love to discuss more on this and hope more good views will be coming up.
