On my 2018 rim brake V20 when I pull the front tire out my forks and chain stays often separate, and the RD with the hanger falls out. Not a big deal though. I slide the front wheel back into position, being careful that the chain goes onto the cassette on any of the smaller gears, and drop the forks onto the hub. I move the chainstays onto the forks in the proper position and slide the QR almost all of the way through. Then, I lift the rear derailleur, give it a 1/4 turn towards the front and pull open the chainstays to slide in the derailleur hangar into the derailleur hanger slot and rotate it around until it locks into place, then slide the QR all the way in and screw in the QR nut. Since I have done it enough times now that it isnt an issue I have not resorted to the ziptie hack.
