It can be so for certain high performance a/c but not air transport category.
Failure modes have to be taken into account. Unfortunately, things go wrong.
In an ideal world all a/c would be designed with all surfaces lifting (Canard?) but we are not in that world.
Yeah, aircraft designed for high manoeuvrability might be designed to be unstable and rely on artificial stability.
Don't start me off on canards - they have their disadvantages
