How to improve Windows 11 in an officially supported way？

I keep seeing people modifying Windows 11 in ways that are totally unsupported - ripping packages out manually, using third party modified Windows installation media, applying group policies to consumer Windows SKUs - all with the goal of 'debloating' Windows. This inevitably leads to a flood of posts about an update 'breaking stuff' when it turns out that the user ripped out Game Bar - which is a core Windows component.
