Pull request description:

  By default, for mainnet, the p2p listening port is 8333. Bitcoin Core
  has a strong preference for only connecting to nodes that listen on that
  port.

  Remove that preference because connections over clearnet that involve
  port 8333 make it easy to detect, analyze, block or divert Bitcoin p2p
  traffic before the connection is even established (at TCP SYN time).

  For further justification see the OP of:
  https://github.com/bitcoin/bitcoin/pull/23306
