Well, that's essentially a crosswalk - where vehicle drivers are required to give ROW priority to those crossing.

Do you realize that by advocating these kinds of facilities for cyclists, you are advocating for cyclists to act and be treated like pedestrians while riding in traffic?

Such advocacy is fundamentally in conflict with vehicular cycling and the interests of vehicular cyclists.

On my commute I have a freeway overpass crossing. Some cyclists use it vehicularly, merging left early, while others ride slowly on the sidewalk, all the way across, and then use the crosswalk to cross. The two systems - vehicular and pedestrian - work fine, and either is available to cyclists. But when you make a cyclist specific facility that requires cyclists to act and be treated like pedestrians rather than vehicle drivers, that's something else again.
