Is the Cart.php library a sign that more libraries are coming?

[quote author="xwero" date="1234898929"]This morning my CI SVN updater notified me a new library was added to the framework : Cart.

I wonder what made the EL developers choose to add that library to the framework as it's seldom requested. Maturity? A shop module? No reason?

It seems the marriage of CI and EE is coming closer and this raises the question, where will CI stop and takes the EE core over?[/quote]

I think necessary also an official authentication library.... for a complete and CI only use of the Cart library
