Not that I’m aware of. I checked with the support team, and they’re not concerned about performance, but think that https://discussion.fedoraproject.org/badges would become pretty unwieldy. But it’s actually no worse than what we already have at https://badges.fedoraproject.org/explore/badges — that page was clearly designed before we had so many!
And from a coding perspective, it’s not hard. I was playing around last night and made a script which can take a name, description, and badge image and upload them here. (And can award badges, too.)
