When integrating a release process within a Continuous Integration (CI) automation routine, it's useful to get some deprecation/warnings messages in the stdErr when invoking "snapcraft upload". For example this: https://snapcraft.io/docs/deprecation-notices/dn11 However, other messages that are not warnings or errors are also sent to stdErr (instead of just stdOut), which forces me to have to ignore them in the process that uploads a release under my CI setup. Examples of these kind of messages: Pushing 'gwallet_0.3.332.0_amd64.snap' [=== ] 12% Processing...- Having them being sent to stdOut instead of stdErr would allow me to fail CI whenever any important message gets sent to stdErr; allowing me to pay attention to deprecation notices or other important stuff happens.
