The problem the Brotherhood have is that they are the poster boys for the fallout series at large, the only time they weren't on the front cover of the game itself was 2 for the Enclave and New Vegas for the NCR rangers.
It does mean that there is little room to do something interesting with them, at least with Bethesda writers. In 3 they tried to have a breakaway chapter going East and more inclined to recruiting for members to a lesser degree than the tactics version causing a split with the hardline Outcasts but Bethesda ruined that themselves with 4 removing a lot of that development to paint them as hardline extremists which with their bad writing, didn't work.
Compare this to New Vegas, a chapter on the decline, hiding from the NCR and one path has them signing a peace treaty with them for survival. There was a lot more to explore with them not front and centre similar to the Enclave remnants.
