Hi Pontificator_extraordinaire!

The objective of our edits was to add a turning lane for the westbound.  Eastbound turn lanes were added not for our routing purposes. Since we were adding the lane tags on the middle part, we also added turn lanes for the other direction. 
In this case, there was no need to correct our edits; it could have simply been supplemented with turn:lanes tags here 35.23287, -97.43024. As it stands, the same value was removed and then added back to this section https://pewu.github.io/osm-history/#/way/1427251581 / https://pewu.github.io/osm-history/#/way/1426776264. I would be interested to hear your opinion on why you prefer removing all changes instead of supplementing the existing edits?
Nonetheless, I understand your perspective. Do you believe that if our changeset somehow includes editing the eastbound turning lane, we should address it completely along the solid lane, is it correct?

Best regards,
Yuliya
