Why are the new TRS Gizmos in 5.4 so bad?

Maybe an unpopular opinion, but I quite like how the gizmo works in general. My main gripe is, that neither snapping nor alt+drag to duplicate work with the new gizmo. Oh and in 5.6 it doesn’t properly work alltogether for me. Can it really be so hard to make a good gizmo? :confused:
