Malleability Fixes - not fixed. just offering a 'opt-in' keypair type thats disarmed from doing malleability (only the innocent will happily disarm)
It is fixed. Nobody has claimed that it was fixed for the legacy keypairs.
its not fixed.
the problem with quadratics /malleability is that malicious people will use it to do mallicious things.
unless mallicious people CANNOT do it. then its not fixed.
EG its illegal to use drugs in countries..
does not mean the war on drugs is fixed by some rule. because people still use and sell drugs.
unless there was a way to permenantly guarantee that no one can sell/use drugs, the war on drugs is not fixed.
segwit is not a war on quadratics fix
its not even a prohibition (think about the 1920's alcohol prohibition)
its just a gesture rule where people can voluntarily move to a gated community that voluntarily wants never touch quadratics. and it wil turn out that the only people wanting to move are the people that never intended to spam in the first place
