It is the accepted concensus practice to split highway= ways where there is a median or other physical separation. This has been explained to you and you insist on mapping as you prefer. This is causing tension with other mappers in your area which is why we map using the consensus patterns and not our own preferences. 

My hope is that you will respond affirming that you have heard and internalized this feedback from your fellow mappers and will cease reducing split ways into single ways with nodes embedded in them. If you choose not to I will have to escalate to the DWG who will then come and place a block until you decide you want to play along with everyone nicely. I do not understand your general reticence. Take a the feedback and we can all move on. We all make concessions of this type to help keep the map a happy place.
