Since this commit:

cbe2dbb    7/6/14 6:05 PM    Raphael Collet*    [MERGE] new v8 api by rco...

all the MAGIC_COLUMNS ( and Database ID (.id) in particular) are blacklisted on topmost level and thus no longer allowed in CSV import. This obviously kills a very nice feature of being able to mass-update records by their DBID.

Any comments on why is that?

And what will go wrong if I override get_fields() method of model base_import.import and add Database ID to where it is not yet present?
