Here is the qt_add_ui roadmap

1. Recommend qt_add_ui as a fallback method for AUTOUIC problems for Qt 6.8

2. After the 6.8 release, use it in internal tools and monitor for any problems

3. Collect feedback from users

4. When confident that qt_add_ui can reliably replace AUTOUIC, begin discouraging the use of AUTOUIC.

5. Eventually, deprecate AUTOUIC and add warning messages where necessary
