We've seen multiple users enable it by mistake and get utterly confused, reporting as a bug that the interface text is garbled. On the other hand we haven't really seen much use of the feature by editor UI developers, so we can likely simply remove it. If there's a need eventually, we can re-add it as a command line option (which is also better than an editor setting as one would typically want to toggle it during development).
