in the case of delegation, I look up @garlonicon's idea
It is based on vjudeu's idea:

what you are doing is bad for the resistance, it makes us to look weak and irrelevant, leaving bitcoin defenseless
Why? Bitcoin is so resistant to changes that sidechains should be introduced by no-forks, because they won't be accepted as a soft-fork. And this proposal is also a no-fork, so you can think about it in the same category as HD wallets and similar BIPs. Bitcoin is so resistant to changes that hard-forks are practically impossible to introduce, soft-forks are very hard to introduce, and you complain that Bitcoin is "defenseless"? The strongest defense is just sticking with what we have and rejecting any new proposals. And you know that people can always do that, and it will only escalate, so more no-forks will be needed to change anything.
