Which has nothing to do with osm or anything in the real world for that
matter?

I do my work in the real world but I only have to show the reasoning if
requested and then only with valid reason, the final product is all I have
to show otherwise.

If the data was challenged that I entered then osm can contact me for the
original data.  In the meantime why are we filling up storage on osm with
data that is not producing the final product ie the map.

No, if someone had better than consumer grade equipment then that should
be uploaded and locked so that it can not be changed except by the person
uploading the data or on request to them.  It would override the consumer
grade equipment totally.

But they are very rarely (less than once a year) wrong.
