Little things that matter in language design
Sounds nonsensical to me... if the annotated code is not in any way performance critical, doing the extra work of annotating it is pure waste.

Although now that I think about it, maybe many of those checks I used to put unlikely() in my code are nowadays pointless, because they call functions that I've since marked with __attribute__((cold)), which should put the unlikely()s there automatically. (But do they? I remember testing that the cold attribute did nothing in some gcc version.)
