My $0.02 We had this model dual-branch when I was at GE and it was problematic. Among other things, the two branches would tend to diverge to a large degree and you ended up just cherry-picking in stuff here and there, which caused even more problems, as well as the model allows the secondary branch to get pretty buggy -- human nature being what it is -- to the point where it's difficult to merge it into master without freezing them both and stabilizing, merging into master, then stabilizing again (small things almost certainly went into master in the meantime -- hotfixes, critical features, etc, while everything was on hold stabilizing the secondary branch). It just double the work in the end, is what I experienced.
