Tbh I don't think any changes will be made to vbulletin.org. Mainly because there's no one available to do so. I like the idea though.
Paul does most of the custom coding here. I can submit this to Jira and list it under vbulletin.org in jira - the worst he can say is "no" just like with anything else in life however if you get this thread riled up and I mean poppin' I'll gladly file it as a normal jira (so non vb.org members i.e. the rest of you can vote on it) and if more want it done then there's more a chance.
I like the idea, like a small notepad area to jot down notes about the mod whether it be a tip or something you encountered i.e. issue and/or resolution etc. Edit: Ohh and perhaps let developer view these notes but not sure about that aspect of it yet i.e. usefulness or what if sensitive info is posted by mistake... hmmm.
