Nah
Anaconda requires you to get an installation image somewhere and burn it
to a CD/DVD. A firstboot package would just add an entry to the usual
boot menu, and work even on a CD-less system. Plus a firstboot could be
split into "manage partitions" "manage lvms" ... tools, while anaconda
only knows about update process.
