Comment 7 for bug 1789502

I'm also looking at dropping the XHasMessages, BackgroundFile and KeyboardLayouts patches, as these are all obsolete with LightDM 1.26 - Is there anywhere else that might be using them?

Does anyone know if the InputSources and FormatsLocale is still applicable and which components use it? If they are still used I'd like to fix those to use the AccountsService extension mechanism - then we can drop the patches.
