Just my five €cents:
My experience with the massive imports in Veneto is, under many aspects,
I have tried in vain to stop or revert them.
There are a number of problems, just to list a few basic ones:

   - we import perisahbale data which are at best remotely related to what
   should be in a geographical database
   - we are importing data without verifyiing them
   - we do not have the manpower to maintain imported data
   - and the most basic one is that data imports are in 100% contrast with
   the basic database rule of keeping and updating data only in one place.
   Importing perishable data from other sources into OSM is simply wrong.
   External data should be linked, but never copied.
