I think this point is controversial, so let's stick with some points
1. In our history of imports, a very small percentage have been good.
2. We have no current technology to keep an import synced with another
data source, so the data goes stale quickly.
3. Many imports are of datasets we don't want in OSM and we have
little/no mechanism outside community vetting to discover that until
it's too late.
4. Most imports are bad, and most imports are left in OSM, which means
we have tons of garbage in OSM. Garbage in OSM makes the map harder to
work with for mappers, for tool-makers and for users.
