That is not how I would describe the issue. There's a number of places where things are mapped as though there is protection where there is not. See for example https://www.openstreetmap.org/way/1297816226 which doesn't exist south of Milk St. This is something I had fixed 4 months ago https://www.openstreetmap.org/changeset/152294610 and have resurveyed today, and will update later. If I find picture hosting, I will share photos, otherwise I am happy to share them by email.

There's also an issue where there is more information in the tags on the roadway than the separate cycleways, and the increasing prevalence of the mapping of separated cycleways has degraded the map for viewing, inspecting, querying, and routing. Specifically, the tags that were not carried over mean that querying the map yields less information. The separation of cycle lanes from the roadway also separates them from the name of the roadway. This in combination with some of the cycle lanes mapped as cycleways that depart and rejoin the roadway repeatedly make creating cues for routing very strange
