> Using some algorithm to take some input and generate a bip39 phrase that you can use with any bip39 wallet sounds perfectly reasonable. I think any method that doesn't use real entropy, but some fake source of randomness, such as a book is asking to be hacked and so is not a reasonable idea. If

I don't see any modifications to the proposal that addresses the issue that miners will always be free to choose their own priority that a few people brought up before. I understand you think it's in the miners best long-term interest to follow these rules, but even if a miner agrees with you, if
