Yes, I do agree.  It was an accidental thing.  One fix, as you
suggest, would be to collapse the packages.

However, there is some utility to keep the shared lib packages
separate.  So I chose to simply downgrade the dependency of boost-dev
on the others from Depends to Recommends.  The boost-dev package
recommends all the other packages on the theory that you can use some
parts of boost-dev independently, but some other parts do require
installing serialization-dev, etc.
