The article states it's just a fork, AKA a separate coin that copy/pastes the current Bitcoin ledger. Even if every dev wants this, that is a "hard fork" (not backwards compatible), and creates a new version of the coin. Ex: if you want to add a smiley face to some Bitcoin log output, you 1) make the change, and 2) nothing happens until 3) miners agree to use that new version.
Look into "Bitcoin Cash", a near identical coin except it has a larger block size. Completely different token and therefore has 0 effect on Bitcoin.
