For the longest time, I had the goal of a no-assist pull up. I got very close, but the reality is I have a torn labrum in my right shoulder and a no-assist pull up is just not something I should do. I do a ton of other shoulder work. In fact, I think it's my work out that has kept my shoulder stable for several years now. I've come close to re injuring ( subluxation on the Grand Canyon) but because the entire shoulder girdle is so strong now, it's prevented potentially bad things from happening so far.
There's lots of other things I can do instead... horizontal pulls, full pushups, a very wide array of other things, so I just accept it.
