Relates to #1566 . Most if not all the scripts have had the non-cosim elements removed. See linked issue. The documentation aspect which is covered in this issue has been split off from the main task as two separate areas of concern.

Duplicated by Remove all non-cosim elements from Documentation (have marked it as completed as it covers the same areas)

Assigned to @hcallahan-lowrisc as he is familiar with this and has been working on removing non-cosim elements from the scripts and tools. He will be familiar with the OT documentation that is touched on by this. @hcallahan-lowrisc can you provide a quick estimate using the (> estimate (value) syntax) on main topic?
