SDC: Add a method to retrieve only components not replaced by others

+1 to this.

Also, for readability and clarity I think the new public method (getActiveComponents) is the best solution. Boolean flags tend to obfuscate what's happening, calls to getAllComponents(TRUE) or similar are harder to read and understand at first sight for newcomers.

I like this proposal. Let's keep in mind that active component depends heavily on the active theme. This is often overlooked, and specially frustrating when listing the components for an admin screen (that is rendered using an admin theme).

Perhaps we ought to add a parameter getActiveComponents(using_theme: 'olivero'). Where the default parameter uses the currently active theme.

oldeb → changed the visibility of the branch 11.x to hidden.

Created the MR because oldeb was not able to, maybe due to missing permissions. I was with him in video meeting.
