So version 3 of the interface will be the first stable and usable one... 
sigh :/

It's just disheartening that the userspace filtering stuff (including 
interface) was disabled rather than fixed, given that that change came 
first and arguably the follow-on change (285e9670) was an abuse of the 
API that was never corrected -- which seems to be tacitly acknowledged 
since everyone seems to agree more than one flag is needed.
