there would have to be precautions, the editors supporting reduced data
download would have to take care that only unreduced data can be edited and
uploaded. Maybe the API-server restituting different ids for reduced data
could help here as well, so even if the data consumer / editor doesn't
implement a special rule and someone tried to upload simplefied data it
would not overwrite the un-simplified OSM elements or could be rejected.

Cheers,
Martin
