• Regarding "Vote Dust Threshold", it seems as if it could be useful though to have some sort of minimum threshold of say 50-100SP before allowing an account to downvote posts.

• Also, for the UI, given the HF19 changes, it would also seem to make sense to offer users a slider once they have at least 100SP instead of 500SP. I'm pretty sure this is a UI issue versus a blockchain issue, but I'm not totally sure. Perhaps someone can confirm that either way.

• Besides that, it does sound like an interesting potential solution to handle at least some of the onboarding issues, especially by reintroducing the mining aspect, which may also serve to partially mitigate potential abuse by granting accounts permanent minimum bandwidth.

Also, while "account creation tokens" may be non-transferable, they will still have potential value that can purchased by other account holders (ie. think randowhale or similar). Not saying that's a bad thing, just something to keep in mind.
