Sencha Cmd adds undocumented/deprecated config to app.js

When using Sencha Cmd to generate a brand new app, I noticed that in app.js, the config "autoCreateViewport" is added. However, the only mention of that config in the docs is that it's deprecated.



Is it a valid config for Ext.application(), as the Sencha Cmd skeleton app would suggest, or is the documentation wrong?



Thanks.
