LGTM, thanks!

Btw I wonder if in the future we could add some error or warning in case someone uses the same approach for frontend specific features, i.e.

  #ifdef __undef___opencl_c_generic_address_space
  #error "Feature __opencl_c_generic_address_space can only be disabled via -cl-ext flag"
  #endif
