That may be the case, but access tags in OSM reflect verifiable legal restrictions, not subjective opinions. Pedestrians use the highway by absolute right unless there is a traffic order and associated signage (pedestrians prohibited, TSRGD diagram 625.1), which is not the case here. If it were the case, it would render 8 bus stops legally inaccessible.

There are tags you can correctly add to help pedestrian routers decide whether or not to use a road:
