Not a very good strategy to avoid bloat... Not even mentioning you will end up with 100 times the number of tools you have now. I would not call such a system more simple, indeed it would be inferior on all possible points.

In a real system, even basic utilities rarely looks like a CS101 homework result. This is perfectly fine, especially in this case the amount of feature in gnu echo is perfectly reasonable, and the size of the executable will likely depends on various header than code size when the code is so small anyway.
