Sorry, but I do not know how to open an issue there. I also have no insight into the way documentation is created and can not make any use of your last sentence.
I already did file an issue at Psych's GitHub repository and was referenced here by Aaron Patterson, and I fear I have not the time to advance this further.
I just think missing documentation makes a rather bad impression.
