Then I misunderstood your message, sorry.

[ You mentioned byte-compile-delete-errors in a reply to cl-defstruct
  accessors, and the 'optimize' entry under (info "(cl) Declarations")
  ties b-c-d-e to the 'safety' quality, which is the same quality which
  affects cl-defstruct accessor generation, so I assumed the same link
  in your reply. ]
