This is still pending, there are a few questions before it would be ready to merge:

• Currently it doesn't look like there are v2 deployments for the networks that are newly supported. Should I get these deployed?
• Uniswap labs mentioned they don't use the governance subgraph, should this be removed?
• I will pull query logs to see what some other common queries are against the subgraphs to populate the query example page.
• There is a lack of unicorns emoji's, should this be handled?
