Users who wish to unstake their RSR from StRSR have to first unstake and then wait unstakingDelay till they can actually withdraw their stake.
The unstakingDelay can change by the governance.
The issue is that when the unstakingDelay is decreased - users that have pending unstakes (aka drafts) would have to wait till the old delay has passed for the pending draft (not only for their pending drafts, but also for any new draft they wish to create. e.g. if the unstaking delay was 6 months and was changed to 2 weeks, if a user has a pending draft that was created a month before the change the user would have to wait at least 5 months since the change for every new draft).
The following PoC shows an example similar to above:
Allow users to use current delay even if it was previously higher. I think this should apply not only to new drafts but also for drafts that were created before the change.
Alternatively, the protocol can set a rule that even if the staking delay was lowered stakers have to wait at least the old delay since the change till they can withdraw.  But in this case the rule should apply to everybody regardless if they have pending drafts or not.
