That's basically my point. I'm not missing anything, so I'm happy if it just gets small / stability fixes, which doesn't seem like it needs a six member maintainer group. That team should go off and do a great job with 'rv' or whatever the next brand new idea is, and just let rubygems sit there with minor updates, same as we do for the ruby logger or date class.
It seems unrealistic to believe that packaging infrastructure can just “sit there,” particularly in light of changing expectations around the bare minimum a packaging ecosystem should do to protect its users. I think a more reasonable assumption would be that the (former) RubyGems team did a good job, which translated to boring normality for you.
