As one of the small number of people that fight the battle, I like the idea of Option 1 (full disclosure: I work for a vendor). From a community standpoint (I'm on the PMC) I'm not strongly opposed to Option 2 although I wouldn't want to be the one managing and releasing the artifacts :) Having said that, unless it remained maintained and released, I feel like it would just be a component graveyard (or maybe more like the Apache Attic), in which case it seems unnecessary and that's why I'm behind Option 1. Interested to hear others' thoughts of course.
