Very well argued!

So maybe what we need is for the structure in the PDB to accurately reflect 
the infromation in the paper. i.e. if you publish a paper which shows an 
all-atom model, or draws any conclusions from such a model, then you must 
also deposit such a model. That seems fair.

I'd also support compulsory depostition of Fobs/Iobs.
