I'm not sure what you mean by "dependency chain" here, I honestly doubt
we have any A->B->C->... chains between packages exceeding, I dunno, 30
in length. Perhaps this means "installing this package installs a graph
with this many package nodes"?  Or more succinctly, "10 largest
dependency subtrees"?

A bunch of that is perl.  The old desktop live images fought pretty
hard to keep perl out, I suspect the sysadmin heritage of the stuff in
the server image will make that a bit harder to accomplish.

One other thing the desktop live image had going for it was a concrete
numeric goal to aim for.  Since we're considering disk space in the
context of cloud images, would it make sense to define a target in
terms of (say) dollar cost of storage in Amazon EBS for a year?

Tsk, another instance of "python3 by default" not implying what we
might have hoped.
