Revision libraries are a better way to provide cheap access to
individual source file trees.
Remember that most revisions are stored as changesets so that the .tgz
is going to contain diffs, not individual source files. Are you
really sure you want to optimize access to those diffs?
(I would guess, (but it is just a guess), that the compression ratios
would be "much" less, not "somewhat" less.)
