So the argument in favour is mostly a pragmatic one. If you can have 2-5x faster code essentially for free, why not just go for it?

I would be easier if the GIL or Cython's use of it was redesigned. Cython just grabs the GIL and holds on to it until it is manually released. The standard lib cannot have packages that holds the GIL forever, as a Cython compiled module would do. Cython has to start sharing access the GIL like the interpreter does.
