What criteria does Bitcoin.org use to choose which wallets to list At this point there are hundreds of Bitcoin wallets available https://bitcoin.org/en/choose-your-wallet

Clicking on a wallet reveals some areas where wallets are compared: 


Control
Validation
Transparency
Secure Environment
Privacy


Some excluded wallets are superior in some of these categories than the wallets listed. Is there a formal review process or criteria for wallet inclusion that someone can reference for me?
I asked Craig Watkins, Bitcoin.org's wallet page maintainer, to comment.  The rest of this answer is his reply.


  Currently on bitcoin.org there are 21 wallets listed (including three
  "hardware wallets").
  
  Bitcoin.org is a community maintained site:
  https://bitcoin.org/en/about-us
  
  Updates to the wallet listings are submitted as pull requests on
  github: https://github.com/bitcoin-dot-org/bitcoin.org
  
  and approval for listing is based on community consensus of complying
  with the criteria listed here:
  https://github.com/bitcoin-dot-org/bitcoin.org#wallets
  
  The pull requests can be submitted by anyone, but are most often
  submitted by the wallet developers themselves.  Reviews can be
  performed by anyone, but are usually done by the current bitcoin.org
  wallet maintainer who offers an opinion on the compliance to each
  criteria listed.  The reviews, discussions, and results for each of
  the current and past pull requests can be viewed here
