I still do believe the current broken peg problem could have been prevented and mostly likely can be remedied now by implementing these two proposals:
As I recall @Indigoman, it was your idea back in 2014 to begin custodial grants of NSR. You have had a big impact on the network and I have a great deal of respect for your insight and perspective.
It looks like the key protocol change you are proposing is to allow parked currency such as USNBT to be unparked as NSR. Would you require this (not allow unparking in currency such as USNBT?). I see merit in the proposal.
