I had a balloon on a string. Dangles turn off the string (created a separate issue for that one). Without dangle the balloon would either sway from side to side with no way to stop it (there was no “friction” setting on the hinge to slow it down), or using weld it would be a firm stick with no dynamic feel to the balloon at all.
I think Hinge would be more useful if there was a friction or damping setting to slowly reduce the swaying effect of “hinge” today. Otherwise hinge is not that useful - things just keep spinning.
