Since this would be something in a software upgrade they would have time to adjust - last time that was also a major source of complaints. However, I think this should be far less of a case because of the fee subsidy rate being so low.
They will have to decide what to do with the OSMO rewards themselves, I think it could be interesting if they decided to keep the staked OSMO for the protocol itself and potentially subsidize users in return.
I think they’ll likely just implement a daily unbonding event and so there will just be a slight lag in their compounding though. I took it to Twitter recently and didn’t have any major feedback against but haven’t heard directly from them.
