I'm still the lead maintainer for the nonce. I believe Faré would like
to see a replacement who is able to give more time and energy to the
task. For that matter, I would, too! But no one has stepped up yet.

I am afraid I don't have much light to shine here. It seems to me that
we have an issue here that comes from using ASDF for two different
purposes. In the case of what I think of as "normal" ASDF usage, ASDF
ensures that a currently running lisp image gets into a consistent state
with respect to software systems, and can be kept in (or perhaps
restored to) such a state as source code is modified.
The bundle operations do something that is substantially different.
They are being used to *construct* a new and different Lisp image, I
believe, and so comparing to the state of the running image may be
wrong. This seems like such a case: the state of the ASDF system and
UIOP in the *running* image doesn't necessarily correspond to the state
of those systems in the image you are constructing. In that case, it
seems to me that check-not-old-asdf-system may be simply inappropriate
as a check in some (all?) bundle operations. But I would be hard
pressed to say when it is and is not appropriate. E.g., presumably it
is appropriate in image building, since any image one builds would
include the current running ASDF. But that argument does not seem to
hold for bundles full of fasls or source code, does it?
I wonder if it is possible that we should move this check out of its
current location, where it attempts to hide out-of-date versions of ASDF
and UIOP from view. Maybe we should instead make an installed version
of ASDF visible to `locate-system` so that any out-of-date version will
be shadowed that way, instead of needing to be hidden from
`locate-system`, as it is now.
In one sense at least, Faré is right that I should be replaced as
maintainer. I have never used any of the bundle operations, and feel
ambivalent about their inclusion into ASDF. They crept in as a
side-effect of supporting lisps that use the C compiler, but they are a
*substantial* increase in the breadth and maintenance difficulty of
ASDF. I'm afraid I have neither the time nor the interest to carry that
burden. I would be happy to yield it to others.
