So you don't think this statement allows to omit run-time effects?

    It is not specified whether definitions made available in the
    compilation environment are available in the evaluation
    environment, nor is it specified whether they are available in
    subsequent compilation units or subsequent invocations of the
    compiler.

PS my earlier definition of cl-declaim had 2 bugs in it, I should have written

(defmacro cl-declaim (&rest specs)
  "Like `cl-proclaim', but takes any number of unevaluated, unquoted arguments.
Furthermore the declarations are registered at compile-time."
  (mapc #'cl-proclaim specs)
  nil)
