As a general note: I believe that the whole spec for that client interface started as an attempt to mimic the field names used on the LJ web form, which was IMO a bad idea in the long term, even without the WTF split on top of it. So I'm all for changing the API spec to something more rational, for DW clients. (Also, if you want to consider DW-LJ compatibility problems and discuss them, you may want to repost this to lj_dev on LJ. You may get a better response there.)
