The "cult of generic metaprogramming" is the very community pushing for those features.

This is pretty harsh. I agree that metaprogramming abuse in application code is a problem, and it's not something that should be advocated. However, there is a big difference between promoting C++ literacy and saying "everyone should commit metaprogramming code at work". The blame for metaprogramming abuse lies _squarely_ on engineering teams with poor quality control, not on library developers who like to push the language to its limits in their free time.

Everyone knows that C++ is a language of footguns. Metaprogramming is one of them; Boost is a mixed bag. Every successful C++ engineering team enforces coding standards to address this.
