Really like it and kudos on launching. Copying GH permalinks to sections of code is something I do about 30 times a day to augment my Slack posts, GH issues, personal notes, Confluence documentation, etc.

I gotta say though, I don't know that I'd trust CodeLink to be around 1-2 years down the track and if it's not then all that work will be far less valuable without the code being accessible through links that will no longer function. I truly hope this project gets traction and becomes a mainstay but until it does I couldn't see myself adopting it.
