Ok, I had a careful think about it, and decided to submit a pull request for a fork at block 257000 to completely remove autohodling in accordance with the Nutocracy motion. It also fixes the bug with matured deposits continuing to earn interest.
https://github.com/HOdlcoin/HOdlcoin/pull/86I hope we'll have a quick review period and then get it deployed asap.
Thanks to everyone who took the time to vote on recent motions, but after consideration I thought merely reducing the period has a whiff of deckchair re-arrangement about it, so I coded for the motion that enjoys greatest support.
