The (lset-difference …) expression above is equal to ‘%base-packages’,
because the third argument is a list of symbols whereas the second one
is a list a packages (so these two sets are disjoint).

You probably meant:

        (lset-difference eq? %base-packages
                         (list libinput avahi bluez))

I don’t know the answer to your initial question though.
