I have been trying to get more detailed information about the usage of control rig in 4.26 but so far documentation is barebone and information pretty basic / sparse.
Are there any plans and dates to provide proper documentation for control rig, or is the lack thereof speaking its volume about control rig being changed down the road again? 
Agree, I’m eagerly awaiting more documentation on the setup events for ControlRig because I can’t seem to get it working for the life of me!
Yeah we also tried fiddeling around with creating our own nodes for control rig, but sadly theres also no proper documentation on the coding side of things so this whole thing feels EXTREMELY inaccessible to us.
