So someone will step in and implement this primitive but then we will realize we
need another primitive to handle the more advanced sha256. Programming languages 

have libraries for this and they do not modify the language to handle every new
feature. So the best solution is to introduce some library mechanism that would 

make it possible to introduce new commands without affecting the kernel.
