Hi, yawfle! 
My name is Kate, and I’m a mapper on the OSM team at Lyft. 
Many thanks for sharing the photo and informing us about reverted changes.
In this case, I decided to disconnect roads, because the passage through this barrier by cyclists or someone else looks unsafe in my view. I suggest applying tag motor_vehicle=no to the segment  with barrier https://www.openstreetmap.org/way/1231579385/history to exclude it completely from navigation for cars.
Another option is a combination of tags ‘access=no’ +’emergency=yes+bicycle=yes’ on the way. Perhaps, it would be also useful to add turn restrictions from alleys to North Cordova Street in order to provide a more comprehensive and accurate representation of the real situation on the map. Please, let me know if any suggestions will be acceptable for you.
 
Regards, Kate.
