"In addition, it looks like Segregated Witness is more about fixing the transaction malleability system than having to do with the Bitcoin block size debate. While it is important to address transaction malleability sooner rather than later, a solution has to be found to solve the block size debate at the same time, without resorting to the semantic game.
There is no reason a small block size increase can’t be done – it takes a minor alteration to the existing code – and implement Segregated Witness afterward. Keeping in mind how a small block size increase has nearly identical disk footprint requirements compared to segwit, and can be implemented in a much shorter time frame, this approach seems to have a certain merit." that is called a "compromise". some core devs like Peter Todd dont seem to know that word
