How long the branches live isn’t the most relevant factor when considering integration problems. How often do you integrate? If you aren’t merging the branch yet, do you at least rebase it daily? If so, you aren’t going to run into integration problems. If you go off on your own and then try to integrate after more than a month of development, then yeah, of course you are going to have diverging work that results in integration problems. That’s why continuous integration explicitly says you should be integrating at least daily. Otherwise it’s not continuous. Of course, you might cause other people problems by dumping more than a month of work in your master branch all at once. That’s why things are easier with short-lived branches. But if you want to avoid integration problems yourself, integrate continuously.
