New Library Review

• Are all the answers in the main description filled out properly and make sense?
• Who maintains the library and how well is it maintained?
• How viable are the alternatives?
• Should we build it ourselves instead?

Once these questions are answered, start a thread in #engineering-chat, ping the @app_deployers group, and call for a vote to accept the new library. Once the vote is complete, update this issue with the outcome and procede accordingly. Here is a sample post:

Hey @app_deployers,

There is a request to add a new library to App that we need to consider. Please look at this GH and then vote :+1: or :-1: on accepting this new library or not.

Seems like this is possibly being split into a few different P/S items - can you re-open if you still need this library with another P/S once that conversation is done?
