I was trying to make a custom module class, which would have provided its own :DEFAULT-COMPONENT-CLASS via :DEFAULT-INITARGS, but

(setf (module-default-component-class ret)              (or default-component-class                  (and (typep parent 'module)                       (module-default-component-class parent))))

means that does work as I hoped it would. The closest I can get is by overriding ASDF::MODULE-DEFAULT-COMPONENT-CLASS method, but that seems fairly icky.

Is there a better way?

ASDF has been using the more traditional method (however arguably less flexible) of specifying default values via initform.

So, in your module class's defclass, use (default-component-class :initform 'my-component-class)

Does that do what you want?
