No plans to support

  • Metadata
    • The metadata 3.2 spec was deprecated.
    • KICL will consider supporting a new spec if one is proposed.
  • STARTTLS (TLS capability)
    • This is an officially deprecated STARTTLS approach, which is silly when the default KICL strategy is TLS.
    • Use the TLS and STS support that KICL has built-in instead.
