You mean the 84" maximum when not contacting alliance zone carpet (which is valid on the bridge)? Or do you mean the bumper zone rulings on Q&A/TU#4?

Last I've checked, there are no restrictions on using appendages, either in the 14" horizontal allowance or in the vertical allowances, to touch the ground from the bridge. (There are restrictions on whether leaving said appendages touching the ground results in a balanced bridge.)
