I am, apparently, one of 12 people with the gold tag badge for
feature-request and one of 39 people with the gold tag badge for
discussion here on meta.se. I hadn't realized this until I cast a close as duplicate vote, then was shocked (and awed) by the power unleashed. Unicorns came from everywhere and swept the question off into duplicate land so fast I was left breathless!
While I certainly don't mind thinking of myself as a feature request or discussion expert, given that you have to tag every question with at least one of the four tags,
support then being an expert in these tags may not mean as much, since they are so general and prevalent. Other gold tag badges would indicate expertise in a specific area, such as
chat, but the required tags are fairly non-specific.
There are only 76 people with gold badges in these required tags, so it's probably not a problem to be fixed immediately, and I'll just have to be more thoughtful about my dupe closing here on meta, but consider removing required tags from these new powers on sites where specific tags are required.
