Dunno. I think that's just how most companies do it, because HR is a shitshow all over the world. (Because it's hard and concentrating it into a department staffed with skilled HR professionals just seems to "solve it" even if the cost is enormous, and one management fix for this deficiency is "stack ranking" in the US. Diffuses legal responsibility, easier to defend, mechanical, etc.)
"Managing out" people works, but that would mean taking responsibility for the decision.
And it's possible - even in the so-called socialist hellscape of Europe - to agree upfront with the employee that the employer can terminate the employment without any wrongdoing. (Even if there's a union, the employer has to agree on this with the union, but employers don't do this, because it would mean taking responsibility for performance, and that would raise a lot of annoying questions throughout the whole hierarcy.)
