This geographic database is a group effort. We do not all have the building plans, nor can we all trust that this will be mapped in the future. This note has useful information, and someone else may want to use it. Maybe not you, but maybe me or another person. Meanwhile, if you'd like to get this resolved, then use your plans (if they're allowed to be used in OSM) to map the building as a construction object, then the note could be obsolete. Until then, leave the information here.
