• https://github.com/meltano/squared/issues/385
• Make sure they match as expected
• Audit the impact of pip_url vs variant vs original variant usage
• Explore the > 2.0 usage thats not able to be attributed. Is it a low percentage?
• Can we also use scrapped git urls as potential matches? This would allow us to attribute usage to non-hub listed repos helping us track what should be pulled to the hub.
• Re-evaluate a high/med/low usage relative to other variants
• How can we show repos that are getting usage but not listed? "this is the only variant listed but another is getting higher usage"
