Without knowing local situation I cannot comment this particular case, but I can tell about mass-imports what I have done myself, spent each time many man-days for conversions, improving scripts, discussions with community etc
1. second largest city of our country full data (streets,buildings etc) import. The city had a few streets before, and person who had added most of them, agreed to replace them. It created positive buzz about "good quality OSM database", but killed local community. 2. Corine Land Cover, nation-wide import. Today I would do it much more carefully, or not at all. It has made more mess and troubles, the only advantage is that medium-zoom rendering looks nicer with a lot of green forests; but high-zoom is terrible and it is very hard to fix it now. 3. National administrative borders (from state source), all levels. This was the only good import so far you could not get the data with field survey. 4. I have also prepared quite good water info - decided NOT import it, keep for manual copy 5. In the pipeline is national address database (should have all addresses/buildings as points). I have permission from source, accept/comments from the community, reject from local post agency regarding including post codes (surprise-surprise). So out of 5 imports maybe 1 or 2 were really "good" ones, if you look it this way. So imports are very-very dangerous and should be done only if there really is no other alternative. My own optimism of re-using existing souces (as anyone with strong background in GIS/geodata would have) to improve OSM has reduced dramatically. But I like the idea that there should be separate shared import-data layer in OSM database (API and editing tools) itself, similar to GPS files. Right now I have several new datasets just as bunch of OSM files somewhere in our HTTP, and URLs are posted to local talk-list, but this is not a good solution, I actually dont recall myself where they were.
