Witnesses are currently discussing in github the possibility of a hardfork. I am posting here because I'd like to hear my followers thoughts on this in the blockchain. I love github and think it's a great place to discuss issues with the codebase, but it's not the blockchain.
Here is the crux of the whole thing explained by 
This same mechanism does not exist in the reverse direction however. If SBD is trading above $1 USD, then there is very little that can be done to push it back down. Witnesses have proposed using a price feed bias to artificially increase SBD production, however this has the negative consequence of violating the inflation restrictions.
One of the main benefits to this change though (in addition to creating a mechanism to support the peg in both directions) is that it will create a process whereby an increased demand for SBD will directly translate into an increased demand for STEEM.
The whole point is to have a way to create ebb and flow of steem value and SBD value to peg SBD at $1.
Please have a look and discuss. I'd like to hear your thoughts. You can also view other witnesses views in GH. IMHO, I like the idea of a reverse conversion with one exception. I think it forces market manipulation on the STEEM currency. In order to create a honestly pegged SBD, this approach artificially creates demand for STEEM which manipulates its market value. It's a slippery slope.
