If Bitcoin Core sticks to calling itself 'Bitcoin Core' and not 'Bitcoin Reference' or just 'the Bitcoin' or similar, and if there is 'Bitcoin Classic', I think we have a pretty level playing field from an 'how-official-do the names of the various Bitcoin implementations sound' POV.
(I also have to admit that I personally like the sound of the name 'Bitcoin Classic' more than 'Bitcoin Unlimited')
