Don't be surprised if they start moving GPLed packages like bash, ruby, and emacs into this free CLI tools download, making OS X "GPL clean".
There is absolutely no reason to move those apps. They're binaries. The GPL only threatens them if the use free code in a nonfree program and don't distribute the source.
The only other option is Apple doing it out of spite, which would be stupid on all accounts.
The GPL isn't the only other reason they might move more command-line functionality into a separate download - OS installation and download size is another.
