@jeffersoncarpenter Note this doesn't say it's needed, just that Segwit does it - which is true.

Segwit does not make malleability impossible. it only affects users that opt-in to use Segwit keypairs for their funds

[MickSHunt]

Segwit disarms transaction malleability only for those opting to use Segwit keypairs, allowing them to make scripting easier to upgrade as well as bringing many other [https://bitcoincore.org/en/2016/01/26/segwit-benefits/ benefits].

shaolinfry. the fixes are only for those using segwit keys.
where as everyone else is still stuck in the 1mb base block and still able to malleate/quadratic spam and do the other things.
many people wrongly think that just activating segwit fixes all the stuff instantly for everyone.
it needs clarification that its not the activation of the block structure that matters, but who is using segwit keys

@MickSHunt BIP148 is an activation mechanism, it's not necessary to detail segwit's semantics here.

[MickSHunt]

but for people to know what they are flagging for. its best they know what they will get if it does activate

@MickSHunt Segwit is a blocksize increase. @luke-jr please close this pull request.

Okay, sounds good. This is just how segwit is defined.
