XMLA read only - read/write permissions on a user/group level

For development purposes it would be very helpful if it was possible to connect to a dataset in write-only mode and "download" measures (or update the definitions) to a local model. Indeed tables could be updated/downloaded this way I think, even calculation groups. I this way it would be possible to freely develop, as all measure definitions are visible etc. At the end the resulting dataset could be used by the owner of the master dataset to import the measures that need to be in production. That would save a lot of "please add me such measure" then getting it wrong, then trying again etc.
