In this thread, Stefan is defining an "Elisp expression" to be precisely 
an S-exp that is intended for `eval'.

So a variant of `read--expression' could be written that does a subset 
of that completion appropriate to the more general context of entering 
an S-exp.  It might for instance be a flag passed to `read--expression'. 
 This answers your original question: it's internal because we are 
still discovering the use cases and desirable interface for it.
