Ah, I think I found some of your technical issues... My impression is that I don't think transaction size should be any issue for Riecoin since we will most likely never approach scaling issues like upstream. I wasn't aware of any issue with zero-fee transactions and segwit, if a miner wishes to mine them I don't see a reason why that is not allowed (that would be a pool or miner setting, correct?).
Segwit's benefits for Riecoin are beyond scaling though, Script versioning and MAST, Schnorr, others come to mind.
I agree, it's easier to just follow the core code than try and change something like segwit.
The current software defaults to zero fee tx if 6 inputs or less, this will change after everyone is upgraded and there will be no zero-fee default.
I'm fine with this, miners can choose to mine 0 fee tx if they want. My beef with segiwt was supposing we keep 0 fee tx, it would make no sense to allow 0 fee segwit tx as they require more space but this is a moot point as it is up to the miners which tx to include (as it should be)
uBlock.it will upgrade it's nodes to this RC as soon as possible.
My only worry is that "All Others" miner goes along with the upgrade as well, since they do not publicly discuss anything we'll have to keep a close eye on if/when they signal support.
