But the `seq-intersection' call will filter out packages that have been
installed (are in package-alist), but not loaded (are not in features).
Wouldn't it make more sense to use:

(seq-uniq (append features (mapcar #'car package-alist)))

Also, what was the outcome of the seq.el pre-loading/autoloading
discussion? Are seq-* functions guaranteed to be available?
