Holy Cow I started looking through ADSF3 (asdf 2.29) and it is starting to do everything under the sun!

Sorry I have just joined this list now, please stop me if I start discussing too much redundant stuff for which I should be reading the archives...

The new functionality like the ASDF/DRIVER compatibility layer, dumping images, and concatenated fasls look really useful and have potential to simplify things on our end a lot. So ASDF/DRIVER has superseded asdf-utils, right? The functions in "10.3 Miscellaneous Functions" of the documentation are the main functions now in ASDF/DRIVER? Or I suppose there are a lot more now -- and the main documentation for the moment are in the source code (understandable). 

For dumping of images, I see for Allegro CL this maps to excl:dumplisp with only a couple of keyword arguments, which is fine for basic dumping of images when there's not a lot of need of fine control. As you may or may not know, Allegro CL has a couple other ways of making executable images: excl:generate-application and excl:build-lisp-image.  For our distributions we sometimes have to call these functions instead of excl:dumplisp.  When the ASDF3 dust has settled a bit and I understand the workings of ASDF3 a bit better, I hope I (or somebody -- maybe somebody from Franz?) will be able to extend the image-dumping support in ASDF to handle these Allegro CL functions as well. But, these functions take many (maybe dozens) of keyword arguments, so maybe it starts to go beyond what a reasonable portability layer like what ASDF is trying to achieve should be trying to provide...  (actually excl:dumplisp takes many of the same keyword arguments as well... so I suppose the answer is that if one needs that find level of control, one had better go ahead and directly call the native version).

Anyway for the time being, if I am using ASDF3 with Allegro CL, and want to use excl:generate-application or excl:build-lisp-image, in order to clear the configuration, is the

still going to work as in ASDF2?
