To me this looks like the ultimate size optimization level.  Before we
get there, we should first see how to get closer to package sizes
typically found on Debian and that alone is a real challenge.

Yeah, that’s also the problem here: we have ‘guix size’ to profile a
package at one point in time, but it’s easy to unwillingly increase its
closure size the next day without noticing.

Chris: does the Data Service track store item sizes (and more generally
everything ‘query-path-info’ returns)?  It’d be great to be able to
visualize size plots over time!
