Note that I only spoke about costs and benefits in terms of runtime,
because I assumed that to be what Andrew meant by costs and benefits. 
Managing multiple profiles declaratively OTOH is itself a benefit that
ought not be ignored!  Also kn log kn is still bigger than k(n log n).

Pierre's "Guix Profiles in Practice" is a 2.5 years old blog post.  If
you can't think of any uses for multiple profiles, you're not the
target audience at this point.
