and I forgot one important point: HOT seems to have disabled the
validator in their iD instance, otherwise the user would have been
warned about overlapping building.
It's a bad idea to turn off the validator and it could explain the bad
reputation they have.

the user has seen satellite imagery in the background and has processed
a small area, so it seems to me to be a correct integration whose real
problem seems to me to be that the real source (data file) is not known.
but the majority of changeset with iD don't have an changeset source
anyway :(
