Not another one of those politically biased threads. Stop feeding into the games played by Ver. The majority of the industry is standing behind the Core contributors and on-chain scaling solutions like Segwit. For example, Segwit has more hashrate after a few days than what the XT/Classic/BU takeovers have managed to gather in over a year.
The community is divided, and that is obvious. However, one side is constantly being toxic and
is now trying to stall via political games. Yes, wanting to block Segwit because you dislike Core, Blockstream, Maxwell or whatever irrelevant reason you have, is stalling.
I'd like to see a dynamic, albeit slightly curtailed BIP106 + Segwit too. I say curtailed, as the doubling or halving aspect of the original proposal could easily become excessive. A 12.5% (or if percentages prove to be a bit messy after a while, then just say plus or minus 0.125 MB) adjustment would prevent any sudden, drastic movements. People still seem fixated on this strange notion that the blocksize limit should be a whole number, but there's no implicit reason why this should be the case. The fees being collected by the miners, as detailed in BIP106's "Proposal 2", should also be factored in to help prevent gaming the system.
I actually like your idea and would most likely support such a hard fork (if properly designed).
