Thanks for the response! You are the mapper on the ground and I believe you if you say its not there. 

Your changeset description implied you were removing it because it was not official, not because it didn't exist. So I wanted to make you aware valid vs invalid reasons to remove OSM feature incase you didn't know. Better to let you know now then have your work reverted by someone else in the future due to a common misunderstanding.

Thanks for your work!
