Monticello is a bad example, then.  Suppose A only works with
ClosureCompiler 1.5, and B only works with ClosureCompiler 1.7.  You
cannot load two different versions of ClosureCompiler at the same
time.  So what do you do?

With package universes, an individual universe should not include
latest versions of packages that are incompatible with each other.
Thus, in the short term, one of these three packages must be left out
of the universe.  In the long run, hopefully at least one of the three
authors is motivated to improve their package's compatibility so that
all three can be added back again.

What do you have in mind for addressing this problem?  Package
universes provides a simple and sufficient answer to it.
