the packages exist for the same reason why your
MS-Word has macros/VBasic and you can write letters,
and other short text documents with it.

The notebooks are text documents with embedded code
for teaching/talks .. and the code is typical something
that you do *once*  and the packages include the code
for something that you wish to do on and on.
