From the limitations section of the wiki page linked in the article: Not all add-in cards have a method to expose their Linux interface name(s) to external port mapping. biosdevname may provide incorrect names for such. Discussions are ongoing on the netdev mailing list to standardize a method of exposing such mapping. Seems like this would be kind of a deal-breaker for any wholesale move like this. I'd be fairly surprised if this got any widespread adoption anytime soon.
