Also, it's always good not to require users to upgrade if they don't have to. Building on El Capitan means users will not have to upgrade to macOS Sierra if they don't want to. Building on Sierra would mean R and packages would not be backwards-compatible with El Capitan.

But it's a tradeoff that also involves the difficulty of maintaining build machines with old OSes, and wanting to take advantage of newer compiler technology. Otherwise R/Bioc would still be building on Mavericks, or Snow Leopard...
