I am thinking about a bigger change to Transwiki / Special:Import.
Status quo: Every import source has to be defined in $wgImportSources for every project separatly and additions have to be requested by a shell bug. This structure makes it impossible to transwiki from every project into every project.
My proposal: Removal of the drop down box from Special:Import and add normal input fields for projectname/abbreviation and language code.
To validate the values compare with the interwiki table && iw_local=1
Questions: 1. Are there any points why such a transwiki (from all into all) would be bad? 2. Can I rely on the interwiki table? Or do we have another source of trustful import sources?
