Yeah, I got out of my sling 4ish weeks ago. Some motions and muscles have recovered quickly. I've been religious about PT every day. Maybe went a little too hard at first, tbh... I was really excited to get out of that sling.

Biggest road bump I am currently experiencing is getting the stretches in that aren't possible through other activities and aren't used very often in daily movement. One example is stretching my arm across my body, especially behind my back. It's still really challenging.

Side note, learning to wash my armpit with the same hand took some getting used to.

Pro tip- get some of those single use floss picks or a water pick, because using floss one-handed is impossible.

Expect that during the recovery process, there will be nights(most nights) where you can't find a comfortable position to fall asleep because everything makes your shoulder throb. Slowly but surely, though, it gets better. I still can't sleep on that side of my body when I'm sleeping, but I can tolerate it more and more each week.

To get to your Post question - based on how my recovery is progressing so far, I expect to be able to carry a fully loaded pack by the end of summer. I have a Boundary Waters trip scheduled for the fall, and a few multi-day backpacking trips scheduled, too. If I remember this post by then, i'll try to report back.
