 Currently the GeoJSON format does this when serializing a feature:

 {{{
    "id": feature.fid == null ? feature.id : feature.fid,
 }}}

 So if the feature object has no fid, meaning it is not known outside
 !OpenLayers, then we set {{{id}}} to {{{feature.id}}} in the GeoJSON
 string.

 We should not. !OpenLayers internal ids shouldn't be written into the
 GeoJSON string, as it may confuse the server.

 In !MapFish we'd indeed like to determine whether the feature is being
 updated or created, based on whether {{{id}}} is set or not in the GeoJSON
 string. Currently !MapFish considers it is a CREATE operation if the id is
 a string, which is far from ideal.
