It's clear there is no consensus on the creole markup for linebreak, but the majority of discussion favoured \n = <br /> and \n[\n]+ as the simplest/most-intuitive. Given this, it seems extremely arbitrary to decide creole 1.0 will break with its previous standard. The further I work into this "standard", the less I find I'm willing to support it.
Creole is not a standard, it's a common wiki markup. The explanation was missing here, so you might get confused. I added that now. Please look into Talk.ChangeLinebreakMarkupProposal.
