I think so.  For example, (require 'format) might just expand into
something like (use-modules (slib format)).  I assume that people
shouldn't call use-modules directly (aside from the initial
(use-modules (ice-9 slib))).

The quickest way to pursue an approach like the one in 1.6 would be to
grab the latest SLIB and then just change the slib.scm in 1.8 to be

  (define-module (ice-9 slib))
  (load-from-path "slib/guile.init")

Then look through guile.init, test SLIB, see what breaks, and propose
any necessary changes to SLIB's guile.init upstream.

When I started doing something similar a while back, I noticed a
number of things in guile.init that I wasn't sure about, so I asked
Aubrey Jaffer about them, and that's what led to the discussion about

If anyone wants to attempt the modularization, I can look back and try
to summarize my conclusions there as well.
