I don't have time and interest enough to fix this bug ­— so instead I
made a bug report:

If someone wants to step up as an ASDF maintainer, that's one bug that
should not be too hard to fix, yet should take you inside the dirty
details of ASDF corner cases, and (at least for now) I'm still
available to help would-be maintainers understand how to navigate the
