This can also include documenting / understanding current browser usage (or we can start a new issue for that, if folks think it's distinct).

One tool for measuring usage over time could be https://github.com/ai/browserslist#custom-usage-data (recommended by Ans) or setting up Google Analytics reports/Google Data Studio graphs to track the browser visits we have on specific pages.

Document in each repo using https://github.com/ai/browserslist

We'd like to have this done in 2 weeks by our next meeting (11/28) so we can share and discuss before moving on to #135
