Reviewed and concluded non-sniffable

• Deprecations for PHP 8.3
  • Unnecessary crypt() related constants RFC rejected
  • Global Mersenne Twister - vote 1 *rand*() functions RFC rejected
  • Global Mersenne Twister - vote 2 *shuffle*() functions RFC accepted, but as it was a vote which was dependent on vote 1, nothing will change.
• Deprecate functions with overloaded signatures
  • array_keys() RFC rejected
• Path to Saner Increment/Decrement operators
  Investigated by @afilina and concluded non-sniffable. See investigation notes in PHP 8.3: Path to Saner Increment/Decrement operators #1985.

Process

If anyone starts work on updating PHPCompatibility to handle any of these issues, please either update the above list (if you can) or leave a comment below, so one of the maintainers can update the list.

Once PHP 8.3 comes out, individual issues should be opened for the changes which remain at that point in time.
