Well, not *everything*, just everything needed to portably bootstrap
the building of Common Lisp code.

That's the whole point of it.

Yes it has. There is a package nickname that says so,
and asdf-utils is now an otherwise empty system that depends on asdf/driver.

The manual has been minimally updated. Writing then debugging ASDF3
took so much energy that I didn't have much left for writing the manual,
especially since things were moving fast while I made many passes
to refactor the API until it was in a satisfying shape.

Yes, for the moment, you'll have to go native if you need the support.
Nonetheless I still recommend you use ASDF3 and respect its hooks
as you dump the image:
(setf *image-dumped-p* (if executable :executable t))
Then use restore-image as your restart function.
If you contribute support for all these options and more to asdf/image,
I would be grateful.

Yes, it will;
but still I recommend you use ASDF3 and its hooks instead (see above).

Throughout history, poverty is the normal condition of man. Advances which
permit this norm to be exceeded — here and there, now and then — are the
work of an extremely small minority, frequently despised, often condemned,
and almost always opposed by all right-thinking people. Whenever this tiny
minority is kept from creating, or (as sometimes happens) is driven out of
a society, the people then slip back into abject poverty.
This is known as "bad luck".
