How important is this for the testnet?

Extremely 😉

Many contracts use/need hashing (if for nothing else, but to determine storage slots) and that is going to be expensive to be had if they duplicate hashing code all the time.

We can include the compiled wasm of this here: https://github.com/ewasm/ewasm-precompiles/tree/master/keccak256

Lets shelve this for now.
