Yes, this is pretty much the same as the base code does it,
just calling do_quarantine where appropriate, possibly multiple
times. Quarantining is in most respects fully independent from
other actions (such as passing/discarding/rejecting/bouncing,
and sending notifications).

You could call:
$r->add_contents_category(CC_BANNED,0);
for each recipient object, and:
$msginfo->add_contents_category(CC_BANNED,0);
once for the whole message, to add CC_BANNED label
to a set of contents categories.
This should be pretty much indistinguishable from
the baseline code doing the same.
> Can I do the same per-recipient if I wanted to?
Yes, add_contents_category is a property of each
recipient (and also a property of a message as a whole,
see 'blocking contents category' in 2.5.0 release notes).

Don't set recip_done to true, just add_contents_category().
If you do set recip_done, you must also set recip_smtp_response(...),
indicating the success status of a delivery that you pretended
to have done.

Looks good.

Additional notifications can be sent from a custom hook,
as indicated in the amavisd-custom.conf example.
Turning off quarantinining is trickier - I can't think
of an elegant way to do it from a custom hook.
I admit it would be useful.

There is no involvement of attachents concept there, all MIME
parts are treated equally. If there is only one top-level MIME part,
so be it, it still has its content type, file type, and possibly
even a suggested name. I think you are using the right approach.
