Yes, `declare-function` *should* follow the same principles as `(defvar
FOO)`, meaning that they are compiler directives not functions to
execute. They affect warnings only in the current lexical scope, and
requiring a file full of `(defvar FOO)` and `declare-function` will have
no effect at all.
[ Side note regarding this *should*: it currently doesn't work quite as
well as `defvar` because its effect is always file-wide, whereas it
should be limited to the current scope. ]
