In my experience, many people will miss the significance of this, or will simply fail to grasp how this is implementing a programming language at all. After all, you're taking advantage of the host language for every single aspect of the new language, even tokenizing/parsing.
More interesting for beginners (in my opinion) are examples implementing a simple tokenizer, parser, and compiler to another source language. This seems to be what closes the gap between programming languages as mystical constructs and programming languages as programs themselves.
This point of view does tend to displease the traditional SICP crowd though :-).
