FWIW, the real benefits of TACO come from generating code that contracts higher order sparse tensors, which are difficult to code by hand and unlikely to be a kernel in a hand-tuned library. The "novel compiler techniques" mentioned on the website enable the compiler to reason about co-iteration through multiple sparse tensors at a time.
