when the generic-function is part of a public protocol then i use
defgeneric. if we're talking about the only method for a
generic-function, and it's not a function only to get some extra error
checking, then i'd not use defgeneric.

(defgeneric startup (object &key &allow-other-keys)
...)

(defmethod startup ((server server-type1) &key ...))

(defmethod startup ((server server-type2) &key ...)

vs.

(defmethod access-slot-with-dwim ((object object-type))
..)

in the second case access-slot-with-dwim isn't really a 'generic'
function, we don't plan of having other methods and the only
documentation we can think of only makes sense in the context of the
method.
