All extensions shall go through the Opcode and Consistency Review before progressing to the Freeze milestone as specified in the Definition of Done Policy

This is a very preliminary list of the extensions up for review and is roughly in the order of how they will be completed.
I will update this soon and add more information - I just wanted to get this started.
Typically we will be performing several reviews in parallel.
