I will say it - the mechanical attachment is unimportant. The toilet should be secured to the floor with caulk and not depend on the flimsy brackets to secure it in place.
Old toilets had four mounting bolts, two to secure the flange to the toilet and two to secure the toilet to the floor. Once the two out of four bolts were eliminated, caulking became the only means to ensure the toilet did not move when bumped.
You said that earlier. I’m out - the only reason I responded is that someone else did. I don’t agree but that’s fine.
