We have all kinds of historical examples, but most of them turned into a major pain sooner or later - my favourite example are the SCSI protocol headers.

Locking us into the strict UABI policies for them just make someone life horrible further down the road. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
