I think that this is exactly what Matthew was talking about.  One
tricky bit here is to know which packages were installed for which
level.  If *you* installed some packages, then the next time you *run*
(not install) an updated racket version you'd be asked if you want to
do the migration.  But if some package was installed as part of the
racket tree (not user specific) then the same question would apply
when a new version gets installed.
