Just my 2 cents: AFAIK, only if you are developing a new software that
requires a specific library (or some of them, like "opencv", for example,
which might not have yet been pulled by any other package) , then, and only
then, you might add them to "world".  Then, when your software is ready,
please ( ;-) ) create a package for distributing your work, with those
libraries as dependencies, and remove them from "world", as they will be
pulled in by such package.

As already remembered on this thread, each case must be checked.
