This will be a change from Linux's model of naming network devices as 'ethX', which has existed for many, many years. Such a change, according to Domsch's comments in the blog, will not provide soft links to the 'eth'-style of naming devices, which again, has existed for many, many years.
Rather than make such an invasive change that will break things relying on 'eth' names, why not soft link *from* eth devices to these new names? "Rejected upsteam"?
Zero backward compatibility is preferred? Users should now create a udev rule?
