Perhaps you're right.

At the very least, we could have added Lisp versions first, and then 
brought them down to C if an occasion where this matters arose some day.

As it is now, I could only find one use of those functions in Emacs's 
source code, and

  (length> default 0)

doesn't really deserve a low-level implementation.
