That is fine when the scale for OSM is intentionally small. But if larger companies want to use OSM as a base for their mapping solution while contributing changes upstream, it will be helpful to have that infrastructure setup for merging in changes without issue. Edit: I am not suggesting the existing OSM community build this, if companies want to do this they will put in the effort.
