In this article under which we're commenting now (https://steempeak.com/@steemitblog/an-open-letter-to-the-community-hf22-5) there is a note in "Commitment to the Community" stating that they are going to reduce the power-down time to 24h. Now this article has been edited and the same note states
Deploy in the next Hard Fork as soon as possible to reduce power down time to 1-3 days in alignment to other mainstream blockchains, while open for discussion for better economic implications.
They changed 24h to 1-3 days, probably it sounds now less outrageous :)
it should have been done a long time ago and restore SBD settlement in STEEM after 24h, as it used to be
Ok, thanks.
