It is obviously also my point of view. How many do we need, so that "point
of view" becomes "common sense"?

You are talking about "asking the wrong question" and in the same context
you state "if our tagging destroys your application, don't use it". 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.
