Anything but a chain split, please. It sucks to think that my (and others) hard work onboarding new folks will be for naught. Both Amaury and CSW have not been helping this case AT ALL.
CSW just wants to keep Bitcoin as originally designed. Amaury/ABC are trying to push untested changes. This will fail nakamoto consensus. Run ABC and get orphaned.
I'm not too thrilled either but perhaps it is a good test. Something like this is bound to happen in the future, might as well know now how the industry handles it.
I personally believe it's a bit too soon to undergo too much tumult. Later down the line is great, but there's good reason why Bitcoin cash is around, it took years to build up.
Anyway, this isn't a trouble: no >32 MB block will be mined in a near future, so raising the limit is not a problem. However, new OP_CODES could end in a chain split.
Only if miners actually include transactions with new op_codes into blocks. The split will happen if part of miners use Bitcoin ABC with canonical sorting, and part do not.
Saying no to 128MB limit doesn't mean there will be a split. Only if a block >32MB is actually mined by nChain, and other miners do not follow it, then we have a split.
