I did.  So tl;dr:  People will try to discredit Bitcoin.

But they already do that so this is not new.

I started out not liking the proposal, got up on the fence, now fully support it.  In fact I now see it as only a first step in the right direction.

I now believe that we must do everything we can think of to protect the fungibility of Bitcoin.  Any attack on the fungibility of Bitcoin is a direct attack on Bitcoin itself.  In fact, I now believe that attacking the fungibility of Bitcoin may be the most expedient, cost effective and preferred method of attack by anyone who wishes to destroy it.

Thanks to everyone who is on top of this.  We should be behind this proposal and considering additional proposals.
