And worth noting the 2015 15-inch MBP they've discontinued had the old non-butterfly keyboards. The old style keyboards are gone, Apple is 100% in on the keyboards they currently have a defect service program on. [1]

(Edit: Though these new MBPs apparently have a new third generation keyboard, so not exactly identical.)
