GIFs within the Unity Documentation

Hey,

I feel that the Unity documentation is pretty good all around with few exceptions. However, I came across the page for Inverse Kinematics and noticed at the bottom it says this:

I feel the Unity Documentation could really be improved with the odd use of GIFs. I feel this is a good example as I do not have the time to follow the guide right now but I would love to see the result.

Is the absence of GIFs within the documentation a rule set by Unity or simply an oversight or did I miss something and they actually do occasionally add GIFs?
