Packages named utils, common, or misc provide clients with no
sense of what the package contains. This makes it harder for
clients to use the package and makes it harder for maintainers
to keep the package focused. Over time, they accumulate dependencies
that can make compilation significantly and unnecessarily slower,
especially in large programs. And since such package names are
generic, they are more likely to collide with other packages
imported by client code, forcing clients to invent names to
distinguish them.
