I've been having consistent success getting points with this in the UK. I am pretty sure it's 100% on offer and 100% credited at CP / HI / HIX in the UK, from my experience.
In the US, it seems that half the time they have a tag to use, they don't actually credit points, and sometimes they also don't actually skip the housekeeping. Never bothered arguing.
Elsewhere I rarely see it as an option.
