Maybe, but I would like to read an analysis of this timer strategy from first principles. The 60 seconds limit is awfully long in practice, given for example lifetimes of NAT mappings. It is counterproductive if packet losses are due to physical layer issues, or maybe under DDOS conditions. Exponential growth of timers may be justified by congestion considerations, but even that would benefit from further analysis.
