Afaik Classic has no plans to adopt SegWit. Is this correct? Just how malleable are transactions, exactly?

Classic Roadmap proposal:
https://github.com/bitcoinclassic/documentation/blob/master/roadmap/roadmap2016.md

Phase 3 (Q3-Q4 2016)
Simplified version of Segregated Witness from Core, when it is available.
Incorporate segregated witness work from Core (assuming it is ready), but no special discount for segwit transactions to keep fee calculation and economics simpl

When I play this out in my mind I see this;

1) eventually SegWit gets out the door and is adopted but if it doesn't reduce verification times then what was the point?
2) even if SegWit does reduce verification times it won't ultimately be enough and a hard limit on sigops will be required
3) the block size limit is adjusted up and up but validation times ultimately dominate the mining process
4) multiple block chain-based applications besides Bitcoin are required to handle the workload in a timely fashion

1) malleability fix + trick to get bit more transactions in block by separating signatures to special data structure for SegWit txs
2) SegWit does not help these attacks
3) you can decrease SigOp limits more for future bigger block sizes to be certain no attack is possible for any kind of blocksize increase
4) it is not unless everyone need to use decentralized currency soon. Time + tech advacement allows onchain scalling for Bitcoin unless we get worldwide demand within 10-20 years (not likely mankind replaces fiat so soon)
