The caret installs the task, not the meta-package, which might or might
not resolve dependencies different.

"Note: The caret (^) was generally required at the end of the command
in older versions of tasksel. It is not required in newer versions of
tasksel.

Note - Calling tasks from apt-get is not documented anywhere. If you
find a page that documents this, please update this page with a link."

IOW it's seemingly obsolete, good for absolutely nothing.
