It's very true that no other holiday achievement set has something that cannot be completed within the holiday, but then Brewfest is the only holiday that has an aspect like the Brew of the Month club, which unfolds over the course of a year. In this one particular case, therefore, it is logical to have an achievement that tracks the participation of that aspect despite the seeming incongruity.
My team is well aware of the concerns voiced by members of the community about this achievement, but we still consider it a reasonable achievement to include in the meta for Brewfest.
