I wouldn't hold my breath waiting for that to happen in any reasonable time frame. It's not just that there's a proprietary Apple CPU (with e.g. power-saving features that might also be more or less proprietary, although I don't know how uniform those are among ARM processors). If there's also e.g. an Apple-proprietary GPU or any other components with no specifications or driver source available, there's going to be endless catchup to play for open source support. And if those components are Apple-only, there's almost certainly going to be no incentive for Apple to release any information to outside developers. Getting code to run on, or even optimized for, an M1 CPU is probably the smallest of the obstacles.
