Sorry I can't offer a knee-jerk reaction to this. I need more time and information to produce commentary of value.
As with sidechains, I will by default fight this feature. But I will also hope that fight is similarly futile and the new feature will prove worthy of adding value to Bitcoin.

How about the knee jerk reaction that death threats aren't helpful?
its not a threat, it's a cryptographically signed message.
to show you noob the cryptography in cryptocurrency, but not so surprisingly all you kid can see is "ofmg de4th threat"!!
