[luzpaz]

IMHO when booting FreeCAD this is useful to see Assembly4 workbench (v0.11.10) loaded
I think we should make this standard for

$ freecad-ppd.freecad

I think ties into and should be part of the booting FC process

• Feature: Add ability to start FC without any addons enabled for troubleshooting bugs (Was: It is not possible to determine which add-on is causing the error so that this add-on can be disabled) FreeCAD#15710
