Just to organise the discussion a bit, perhaps it should proceed in 5
steps (perhaps partially simultaneously):

  1. Agree on WHAT INFORMATION needs to be provided

  2. Agree on HOW IT SHOULD BE DIVIDED UP (all information about one
     author grouped together, all addresses together, leave both
     possibilities open,...)

  3. Agree on a SYNTAX (keywords or not,...) and requirements on how
     they are to be interpreted by various .cls (unused things must
     be understood but annoyed,...)

  4. Additional items: should `unwanted' commands be redefined to give
     error messages (to prevent the author attempting visual formatting,
     for example, or using \thanks,...),...

  5. Implementing all of this
