Because more than likely it will be more efforts than doing the same work in
the native language, forcing certains designs [1] up to high-level-language
developers throats, and possibly less stability (segfault, memory corruption,
memory leak, ..) specially in development phase.

[1] lack of separation between IO and pure functions, file descriptor versus
stream, C memory functions instead of GC based, and probably lots of other
things easily accessible from high level language.
