And yes, that is exactly what you just have said. This footway tagging is in fact destroying information. It is not correct data as it misses information and it somehow removes information that was already there. So everyone who uses this tagging is deleting correct data. In OSM everyone is allowed to use any tag he/she likes as long as it does not conflict with any existing data nor invalidates or removes it. If you (for the avoidance of doubts: "you"="everyone who uses this tagging") used some new tag and not highway=footway, this all wouldn't be a problem. But you want it to show up in the renderers (tagging for the renderer) and some routers (tagging for the routers). So before you (in the meaning as given above) start pointing fingers at someone ("disrespecting the work of others") you should first look into the mirror.
