I would fully support that solution. I am currency agnostic, so if "BU-altcoin" is done that way (without premine or ICO or so)
No one who really supports BU would support that, as we obviously want the legacy blockchain and everything that comes with it, including an undiluted asset. We want
Bitcoin to scale , not an alt.
All exchanges alredy said it's gona be an alt. So goodbye taking over chain. After fork BTU will be like any other shitcoin like ETH, DASH and etc.
