But to my understanding, the bottom line is that Fusion is not capable of mirroring a part with its necessary editing statements--what is called a "mirror" command in fusion is not far removed from just a non-editable static pixel copy.
To the first part of that statement, the answer is "yes", Fusion is not capable of this kind of mirror. If you think about it, you should be able to see why, and why (to the best of my knowledge - I could definitely be wrong) no other CAD system does this, either. Creating a "mirror recipe" for the general case of any component is quite a challenge. Each sketch would have to be re-created, but in a mirrored orientation. Each feature would have to be evaluated whether it needs to be mirrored or not (for example, an extrude might have to have its distance negated, or a workplane at angle might have to have a complement angle, but both of these would depend in the geometry orientation with respect to the mirror plane). As an exercise, try doing it manually - I suspect it would be very difficult, and maybe even more so programmatically. Not impossible, obviously, but very hard. While mirroring the "results" (the bodies) is quite simple - a mirror transform can be applied to the geometry.
The second part of your statement, in my opinion, is a bit of exaggeration. Clearly a mirrored body result is much more useful than a pixel copy. It has mass, it has geometry, that component can be connected to other components with Joints, etc. All CAD modelers that I am familiar with work basically the same way, so clearly there must be some value in it...
