I'd like to add my counter example to this: all constructions of off-chain protocols that we know to this day require a repudiation period, during which other parties can intervene to correct or penalize a misbehaving party. This period is enforced in all cases by a delay expressed in blocks. The unpredictable block generation rate means this mechanism is almost impossible to test on testnet, making it's utility for offchain protocol testing dubious if not outright void. While a better behaved testnet is no guarantee that it will give rise to a persistent ecosystem that allows more extensive real world testing on testnet, I'd love to have at least the option. TL;DR: addressing the difficulty reset would be much appreciated.
