here is how i evaluate the kcc-12 proposal in a second pass.
i sketch a user journey, observe flaws on existing web3 platform, see if my user journey fixes it, iterate.
once i have a viable sketch, i take kcc-12, see if it **enforce** this flow. if not, it needs changes.
kcc-12 should also be taken from a UX perspective, and we have a lot to learn from, lot of challenges to crack produce-wise.
