At one time I worked for a carrier whose base was 8000 feet amsl.After quite a few take off and landing tailstrikes on the big jets, only Captains were allowed to conduct landings.There were still landing tailstrikes going on however the frequency reduced by 75%.As I was/am a quite experienced instructor, I let some copilots do the landing, once I had observed them and determined that they were competent.I immediately understood why the Managers put this policy in place.Several times, I had to take control during the flare or earlier as the required touchdown accuracy was not going to be met plus the pitch atttitude was creeping up too close to the tailstrike range.I stopped this "act of kindness" and just did all the landings myself.These types of operations are best conducted not only by the most experienced pilot (usually the PIC), but also by the pilot with the most exposure to doing it.
