I've seen the same claim made about the more obscure features found in application frameworks, and in both cases the problem is the same: there will always be that one guy on your team who takes delight in finding a complicated and mentally burdensome solution to an otherwise simple problem, which requires everyone on the team to at least be aware that certain constructs exist. It's great that Typescript is catching on, and we're starting to adopt it in my team, but I hope the TS people don't think they can keep adding new features to it in perpetuity, otherwise it's going to turn into C++.
