Thank you for the explanation! I will remove the xref to sfsmisc
(because it does not make sense to suggest that package). The three
other still available packages all depend on or import DoE.base. Thus,
if I incorporate them in Suggests, I will create a circular dependence
structure. Doesn't that create problems?
