I personally appreciate the minimal changes, and often encourage development to be done this way - when it needs to be released quickly. But does this need to be released quickly?
- maybe the proposal should be renamed segwit 8mb and be discussed solely in terms of block weights.
- a high consensus hard fork is probably preferable to a low consensus soft fork, however there is nothing to indicate that segwit as it stands isnt already very high consensus except for a handful of pool operators protecting fee income.
- miners who currently object to segwit while pretending to like larger blocks will find some excuse to object to this too.
- Given the challenges miners seem to have in flipping bits, I expect any fork that requires 95pct hash power to be vaporware.
